I decided to do a clean install of Big Sur on my iMac.  In doing the install I erased both the system volume and the data volume.  After the clean install, I installed the the Sonos S2 app.  I have FLAC music stored on my iMac in the Documents folder.  I know what has to be done to have Sonos recognize the path to my music.

In System Preferences > Security & Privacy > Privacy I put the Sonos app in Accessibility and in Full Disk Access.  However, the SonosLibraryServer does not appear when I try to find it to add it to Full Disk Access.  What’s strange is that a search on my computer doesn’t find it either.  Can someone tell me how to add it to Full Disk Access?

All of my FLAC music files are in a folder called FLAC Music. I know that I have to grant Sonos Read & Write permissions.  However, Sonos is not appearing under Permissions.  Can someone tell me how to have it appear?  Thanks.
