Exhange online shared mailbox in Mail on MacOS

Dear community

I am trying to add a microsoft 365 shared mailbox into Mail but it does not work.

This shared mailbox does not have public ID so I have to log in with my own account.

So when I add a new account,

1. I select exchange account,

2. I enter the shared mail box,

3. A pop up opens with Microsoft 365 log in page, *

4. I click on connect with another email, *

5. Put mine, *

6. Pop up close, *

7. Mail create the account of my mail own mail box and not with the sharedmail box + my own as ID.

* it works this way with Outlook for Mac.

Does some has a solution ?
