How can I make an Android app compatible with BrailleBack?

I'm looking to make the Android app I work on more accessible, and was wondering if we need to do anything special to make it compatible with services like BrailleBack so it can be used with braille readers like this one: https://uk.optelec.com/products/abc-640-en-uk-alva-bc640.html

We've already used tools like the accessibility scanner to help us identify changes that can make the app compatible with screen readers. Can anyone recommend any tutorials, etc. that can help us build compatibility with braille readers and services like BrailleBack? Or is it just very similar approach to services like TalkBack, technically speaking?

I've tried looking through Google's developer documentation and accessibility support, but no luck.

It would be great to have an app that is better prepared for visually impaired users. Many thanks :-)
