If you use Teams, you are probably aware that end-users can suggest/request a feature from Teams clients (desktop, mobile, web)
NOTE this menu is not available in GCC, GCC High or DOD tenants
Well, Teams administrators now have the ability to manage the availability of this menu to end-users
To manage it you need to create or edit a Teams Feedback policy using Teams PowerShell module (available here https://www.powershellgallery.com/packages/MicrosoftTeams/)
Connect-MicrosoftTeams
To edit an existing policy
Set-CsTeamsFeedbackPolicy –Identity <policy identity> -UserInitiatedMode disabled -ReceiveSurveysMode disabled
To create a new policy
New-CsTeamsFeedbackPolicy –identity <policy name> -userInitiatedMode disabled -receiveSurveysMode disabled
Grant-CsTeamsFeedbackPolicy –Identity <user email address> –PolicyName <policy name>
Once assigned (or updated) it may take some time for the policy to be applied
