{#control-topic-visibility-channel__ul_amd_lvs_rdb}

## About this task

In your condition script for the topic, use a context variable to identify the
messaging channel that excludes this topic.

## Procedure

1. Navigate to AllConversational InterfacesAssistant Designer.
2. Select the Asset library tab.
3. Select the topic for updating or create a new topic.
4. Navigate to the Properties page, and open Who can access this topic under Advanced properties.
5. In the Context section, select Condition followed by Add Condition.
6. Enter a condition script that identifies the messaging channel (Slack or Microsoft Teams) from which the topic will be excluded.  
   You can use the following example script, which contains the vaContext.deviceType variable, to identify the messaging channel that excludes the topic:  

       (function execute()
       { if(vaContext.deviceType === 'Slack' || vaContext.deviceType === 'Teams'){
       return false;
       }
       return true;
       })()

7. To save the topic properties, click Save.

## Result

Publishing the topic deploys it to the Virtual Agent messaging channels, except for the Virtual Agent channels that you specified in the topic condition script.
