Thanks for reporting @bnjbvr.

sendMailFromUser needs the to field, sendMailToUser needs the from field, so if we want to send a message from the user to the user, the application needs to request the permission to access User.

Having a way to send a message from the user to the user may be useful.

But keep in mind that a lot of messages will be marked as spam if the sending domain is not allowed to send messages for the user email domain. sendMailFromUser may not always work.
