file open intent and MANAGE_EXTERNAL_STORAGE permission

On Android 12, Google TV, ss a user, using Cryptomator app I am trying to set the location of a local file. The issue is that when it tries to open the file it says "you don't have an app that can do that"

I tried using ADB to grant the MANAGE_EXTERNAL_STORAGE permission to Cryptomator. I also tried installing several file explorers.

Any suggestions?
