Zoom app with microsoft Teams

Hi, I have added zoom app in Microsoft teams and launched it . It goes through my SSO login prompts and consent.  However , expectation is that TEAMS already logged on with SSO, zoom has to skip these steps.

1. is it possible to integrate zoom SSO login with Teams / AD ?

2. How to disable the Phone TAB , it is visible after launching it in TEAMS , however we just need meetings only.

Any help is much appreciated!

thanks
