Current situation:
--Recipients of ProtonMeet invitations currently receive the invitation/email from the main Proton Username.
--As the sender, there is no option to change the invitation sending address to a different existing identity/address.
--This causes confusion if the sender usually emails the recipient from a different identity/address.

Request:
--Allow the sender to toggle and select any of their other existing identities/addresses from which to send the invitation.
--This functionality already exists for sending emails.
