Shared music folder for multiple profiles

Hi, I’m looking for a way to share my music folder (SD card) with different profiles (work vs private). I use Mediamonkey as a player and for syncing with my music collection.
Has anyone done something before? I struggled to get this up and running on my OnePlus6 but had it working on the previous phone (can’t remember which one it was :wink: )
Currently I’m trying to change access rights with TotalCommander but it’s not accepting the changes, not sure why yet.
Any idea or explenation is highly welcome
Cheers
M.
