Beta 11 - Shared mailbox Microsoft 365

I’m currently testing eM Client 11 Beta, version 11.0.196.

I’m using a Microsoft 365 account and I’m trying to add some shared mailboxes, but I can’t find any option to do this in the new version.

In previous versions, there seemed to be a way to manage or access shared mailboxes, but in version 11 I can’t find anything similar.

Could you please let me know how Microsoft 365 shared mailboxes should be added or accessed in eM Client 11?

Is this feature currently supported in the beta, or is there a different procedure compared to previous versions?

Thank you for your help.
