Windows 10; MS Teams in default apps not listed

we are planing to rollout MS teams as default phone application in our environment. so MS teams has to register as default app in windows for several protocols for voice-calls (callto, tel, im.....)
in most cases, teams is registering these filetypes / protocols automatically. and we are also deploying the default file types with a group policy.
but on some clients we have the behaviour, that MS teams is not visible in the default-app view. so there is no possibility to register the app.
uninstall and reinstall MS teams did not solve the problem.
any thoughts about this? is there a possibility to re-register MS teams as application properly? (registry-key, ps-command?)

    For a company I had similar issues, but with other programs.
    What I would recommend:

    • Uninstall script for teams private and teams work (as they are 2 different programs)
    • Clean out the register with a script
    • make an install script for teams for work
    • apply your protocol changes

    Make sure you leave enough time-out time between running these commands.
