Send email on behalf of

I have got my company's IT team to set up a Shared Mailbox.
I can use `get_business_outlook()`, and then the methods `create_email()` and `send`() successfully.

Now, IT have created some other email addresses and have set them up as "Mail enabled security group" so that these can be used to send emails via the Shared Mailbox.
However, I cannot find any documentation on how to send on behalf of the Shared Mailbox.
I want the sender to be the individual email address and not the email address of the Shared Mailbox.

The use case is that there will be multiple Docker Containers running in Azure that will have their own email addresses.
The architecture that has been defined is for all these to send via the one Shared Mailbox.

Start with the documentation for get_business_outlook(), create_email(), and send(), then trace how Shared Mailbox sending is currently described. Verify the supported Microsoft 365 setup for sending on behalf of another address, and document the required usage and permissions so the individual sender address is clear.
