How to connect an android phone to Qubes in 4.3?

I connected my android phone to Qubes 4.3. I allowed file transfer. I got a box saying “Failed to mount. Volume doesn’t implement mount.”

I wanted to attach the phone to an AppVM. I could not find it in the device list.

I would like to copy the photos from the phone to an AppVM. How can I do that?

I am new to Qubes and trying to learn and read this forum posts. Here Who can help me how to connect a notebook / Qubes-OS with the cell phone Samsung Android (Galaxy A72)?
