Teams meeting - to show a shared mailbox name, NOT real members

Hi All,

There is a group of several people added to a shared mailbox named "Technical group 5" with the following permissions:

• Full Access
• Send as
• Send on behalf

Of course, these people can send messages as the shared mailbox email address and in this case their personal email addresses are hidden for the recipients. 

QUESTION: Is it possible to hide their personal information when participating in the Microsoft Teams meetings the same way as for exchanging email messages described upper?

So, as requested, in a Teams meeting all participants see "Technical group 5" but NOT the real member of this group, currently taking part in this event.
-------------------------------------------------

I tried 2 ways:
--- Creating a Teams meeting from a shared mailbox like this way - https://answers.microsoft.com/en-us/msteams/forum/all/create-a-teams-meeting-from-a-shared-mailbox/491628f5-9895-42e2-96bd-87947f574a74
--- Adding a shared mailbox as a participant of the Microsoft Teams meeting

But unfortunately, in both cases I couldn't "hide" the real members of "Technical group 5", all the meeting's participants see the real person, not the requested shared mailbox name ("Technical group 5")

Please share your opinion or experience in this area.

Thanks !
