More Than One Non-Business Account in Edge Mobile App

I have a Gmail email and have set that up as an account in Edge so that I can access the same settings I have on my laptop.

I am also supporting my mother's partner, but he has a BT email account and currently, we cannot have more than one non-business profile in the mobile app when we can in the laptop app.

This is possible with Chrome, to have more than one Gmail email account set up and syncing (obviously not a BT email account in Chrome).
