How to get minecraft running on my device without a microsoft account

Ok, so I just want minecraft java edition running on my Retroid Pocket Flip 2. Which from a hardware perspective is identical in everyway to the Retroid Pocket 5.

I can use Game Native to get PC games running.

My device also came with PovavLauncher. I don't know what it does, but it's minecraft related. Although it appears to be an android app.

Does anyone know where I should look for a guide?
