Do yourself a favor and check out Lyrion. Use piCorePlayer to install Lyrion (the server) and Squeezelite (the player).

FOSS, actively maintained, and a much better experience IMO. Tried it back when I was an active Volumio user back in 2020, fell in love instantly, and have never looked back

Mom, you just don’t get it! You don’t need a remote to look for the movies! You just gotta ssh into the streamer and run a MPV command! Stop calling every night saying you can’t find Happy Gilmore!
