As stated in the last update, the ability to use multiple Teams accounts at the same time is being implemented in stages for Desktop. Faster tenant switching functionality on the Windows client has been rolled out to the public ring fully, and Mac will begin rolling out soon. Work is in progress on cross-tenant notification improvements, and support for multiple accounts on desktop will follow. We’ll keep you posted!
Note: The ability to use multiple Teams accounts at the same time is supported on iOS & Android today.

I found Team desktop app has multiple tenants support but it is inconvenience to switch between them. Furthermore, it takes time to switch.
I would suggest to have left icon with custom-able name in Teams. Such as Teams - TenantA, Teams -TenantB.Ky Ho supported this idea ·
