Not root drives aren't detected, nor listed

Good morning.

I have been trying for such a great time to make Umbrel detect an internal hard drive which is not the root one. However, I am not able to use it throughout UmbrelOS pannels. I can write on it via SSH or external apps, but Umbrel refuses to recognise it.
I think, taking care of internal hard drives, as backup drives or extra storage, would be useful.

Thanks and have a nice day!
