Need to strict Teams on mobile devices

Hello all,

I am trying to put together a conditional access policy to only allow mobile Teams app access for certain users and restrict the rest of the users to the office location only.

Am looking at a block policy to block all network locations and only allow connection for users from the Office desktop.

However, when I go in to the included apps section of the policy, Teams is not listed. Only "Teams Service" and "Teams Shift" is listed. 

If I were to block Teams Service/Shift in the selected apps, does that block Teams app itself?

If so, would that cause any functionality issues with other apps like Outlook?

TIA
