SSO sign in before launching the meeting

Hi,

We implemented SSO sign in for zoom with Azure AD.

For some reasons, users' zoom app on PC may be logged out for token expiry.  This is fine as by design.

But if these users click the zoom link to join a meeting, they would show up as guest which means the zoom app does not require them to sign in to the profile before launching the meeting.

Is there a desktop setting or registry setting to fix this behaviour such that all corporate users should sign in to the zoom app via SSO automatically before launching the meeting?

Best Regards,

Joseph
