Configure conversations for Collaboration Manager
You'll need to configure the settings value to be able to use conversations in Collaboration Manager for Loans.
Retrieve the Channel ID of the Teams channel where you want to add the Collaboration Manager for Loans app. Select the ellipsis (...) next to the channel from the list in Teams and choose Get link to channel from the menu.
The URL has this format: "https://teams.microsoft.com/l/channel/<Channel ID>/<"Channel name">?groupId=<"Group ID">&tenantId=<"Tenant ID">". Decode this URL-encoded channel ID. For example, you would change "19%3acbe3683f25094106b826c9cada3afbe0%40thread.tacv2" to "19:cbe3683f25094106b826c9cada3afbe0@thread.tacv2".
To set the Channel ID value, select the Settings solution that you created after deployment in the Power Apps Solutions tab.

Provide the Channel ID value that you decoded in step 2 by selecting New > More > Other > Settings Value in the solution explorer.

In the Settings Group Id field, press Enter and select Collaboration Manager for Loans.
In the Settings Definition Id field, press Enter and select Channel Id

Select the Save & Close button on the top toolbar.
