Registered MuseScorePro account on PC > How To make that account appear for MusescorePro Android app ?

Hello,
I am a registered MuseScore Pro user working usually on a Windows laptop.

Now I would like to be also able to use that account for using MuseScore app on my Android phone.
But... I see no option on the Android MuseScore app to enter me as an already registered user.
Help ...!
