Azure Ad - Share email inbox with group of users

Question

Hello all,

I have this specific challenge where I have a role being applied to a group of users.
A specific group of users should have access to a shared email inbox, so a user that's in that group can pick one email and handle it.
This means that the logged in user is authenticated using SAML on an application and needs to list emails from other inbox.

What's the best way to achieve this?

Is there any possibility to share a specific inbox with only a group of users and when accessing via graph API, allow the user to get the emails from this shared inbox?

Thank you.
