| Property | Description |
|-|-|
| com.glide.cs.doc_qna.va_attachment.max_attachments | Set the maximum number of attachments that can be attached at one time for the assistant. Default value = 3. |
| com.glide.cs.nass.synthesized_response.disabled_popover.hide | Hide the popover for disabled catalog items for Now Assist in Virtual Agent and Now Assist panel's enhanced chat. The default value is false. |
| com.glide.interactive_view.enabled | Open an interactive side panel view next to the chat window. The default value is true to activate AI Experience on your instance. |
| sn_ai_websearch.perplexity_model_name | Specify the Perplexity model to use for web search. The default value is sonar. |
| now_assist_va_search_results_output_type.list | Turn off regular results and only have Genius Results shown within Virtual Agent. Use the system property to access the Now Assist Search Results Output Types table. By default, regular results and Genius Results are shown for all channels (Android device, iOS, Web Client,Now Assist Panel, and Microsoft Teams). In the Search Results Type column, select Genius Search Result. |
| sn_nowassist_va.enable_nass_show_all_option | Displays the Show all options link in enhanced chat and enhanced chat's full-page experience. The default value is false. |
| sn_nowassist_va.display_default_catalog_image | Show or don't show the default cart image if a catalog item doesn't have an image set in its record. Value = true shows the default cart image. This is the default value. Value = false removes the default cart image. Note: A catalog item that is associated with an image continues to be displayed irrespective of the system property. |
| sn_nowassist_va.enhanced_chat_pin_enabled.\ | Create a system property to enable pinning a chat window on a portal. In the system property, \ is the URL suffix for the portal application. For example, the system property for enabling a chat window in Employee Center would be sn_nowassist_va.enhanced_chat_pin_enabled.esc. By default, pinning a chat window is enabled for Service Portal. For all other portals, create the system property. For a list of URL suffixes, navigate to AllService PortalPortals. |
| sn_nowassist_va.show_view_more_for_synthesized | Show the Need more help button in a standard chat conversation. The Value field is empty by default so the button doesn't appear. To show the Need more help button, enter regular, clarification, or regular,clarification. * regular: The Need more help button appears only for synthesized responses. * clarification: The Need more help button appears only for clarification responses. Clarification responses typically occur when an end user's response is too vague and clarification is needed for a more targeted response. * regular,clarification: The Need more help button appears for both synthesized responses and clarification responses. {#nava-sys-props__ul_cqb_xjw_nfc} |

| sn_nowassist_va.synthesized_autostart_items | When synthesized response only returns a singular action, configure whether to automatically launch the action. By default, only Virtual Agent topics and agents automatically launch. You can configure this for whenever synthesized response returns a single conversational catalog item, a single Virtual Agent topic along with Knowledge Base information appears, a single conversational catalog item along with Knowledge Base information appears, or an agent response with sourced Knowledge Base information appears. * Type: string * Default value: topic, agent, agent_with_sources * Location: System Property \[sys_properties\] table {#nava-sys-props__ul_alq_cqx_jdc} |
| sn_nowassist_va.use_planner2_response_as_fallback | Set to false (default value) to use the Virtual Agent fallback message when an answer cannot be found. Set to true to use an LLM-generated fallback message that is more specific in response whenever an answer cannot be found. |
