We recommended pinning the app directly to the task-bar in MS Teams as shown in the video above. However, after the Microsoft Teams and the Coachello administrators have enabled the Coachello app, end-users can install the app themselves if the app permission policy that's assigned to them allows it.
Open Microsoft Teams.
Click on Apps in the bottom left corner to go to the App Store.
Search for and select Coachello (or scroll through the store to find it).
Click the Add button to add the Coachello App for Teams.
Click the Get Started button.
When prompted, sign in with your Coachello credentials.
Allow the Coachello App for Teams to access your Coachello account so we can bring all necessary information from Coachello into Teams.
