Hi imughal
If you're using Send an email from a shared mailbox (V2) for this generic email, you will need to have permissions to the generic mailbox to send on behalf of it for the flow to work (delegate access).
See if this article helps.

Doing that should resolve the access issue. I use this action a lot in my business flows.
