Box Cloud and Cryptomator sync (specifically Android Mobile App)

I have a vault in box cloud that I can access through my desktop. However, I am not sure how to connect the vault from my android phone on the mobile app.

Could someone share details on how to do this?

Seems like box.com does not support WebDAV.

And the api is not jet included in the android app

Is the only solution to switch storage providers?
