It just needs the user to log out and back in before Teams shows up. In practice, occasionally even this fails and the user has to run the installer manually, but usually it works. Teams doesn't show up until the next time the user logs in. After the next login, you should see a second line item in A/RP for Microsoft Teams. The result of this is that after a new O365 installation, You should see a Teams machine-wide installer in Add/Remove Programs. The way it accomplishes this is that the Teams machine-wide installer places an ActiveSetup registry key that's designed to run the user context installer once per each user the first time they login.

It can't actually be installed machine-wide it has to be installed into each user's profile. Now, the problem is that Teams is user-specific.
