File Picker user input control

Use the File Picker user input control in a Virtual Agent topic to prompt a user to upload an image or any file type. After the user uploads an image file, the image appears immediately in the Virtual Agent client.

All file types are supported by the file picker, except the SVG format for image files. Although the image can be high resolution, the image displayed in the Virtual Agent client is scaled based on the aspect ratio. Images scale to fit within the chat window.

In Microsoft Teams, a file can be uploaded through the paper clip (attachment) icon, or using drag-and-drop. Copying and pasting only works for image files. Users can share attachments on Microsoft Teams through the Virtual Agent file picker user input control, and by sending attachments while chatting with a live agent. Multi-attachments are supported for both live agent and file picker scenarios.

Learn what the live agent picker scenario supports or doesn't support:

• Supports multiple files.
• Doesn't support the SVG format for image files.
• Supports a combination of text, files, and emojis. However, orders may show up differently between how a user sends these items versus how an agent views these items.
• Doesn't support formatted text.

When a file upload is in progress, you can't upload or enter text for the live agent picker scenario. The uploaded files go through a virus scan and validation.

Confirmation messages
Input completion confirmation	Bot response shown to the user when the node interaction is complete. The message can be either a text string or a script that returns text. For example, if you're using dot-walking: Thanks, (Input Variables > Username)! Or if you're using a script, the acknowledgement might be: Thanks, {{vaInputs.username}}!
Default value confirmation	Message that asks the user to verify that the value in the Default value field is correct. This message is used instead of a value in the Prompt field. It can contain either a text string or a script that returns text. For example, if you're using dot-walking: Are you (Input Variables > Username)? Or if you're using a script, the confirmation message might be: Are you {{vaScripts.lastUsername}}?.
Hide or skip this node
Conditionally show this node if	No-code condition statement or low-code script that specifies a condition for presenting this node in the conversation. The condition must evaluate to true.
Allow user to skip this node if	No-code condition statement or low-code script that specifies a condition for letting users skip this node in the conversation. The condition must evaluate to true. You can set this field using either the condition builder or a script. When this field is active, the node presents the user with a Skip option in the Virtual Agent conversation. Alternatively, in an LLM topic, you can reply with an utterance such as I want to skip this question.
Skip reprompting if	No-code condition statement or low-code script that specifies a condition for letting users skip reprompting in the conversation. When a preceding node is revisited through a topic loopback or Dialog Act, the Virtual Agent bypasses this node and automatically retain its original value.
