obtain lyrics howto?

[MarcoA]

Hi all, I am new to JF but quite satisfied with my pi5 install, but I cannot get any lyrics for my albums, songs

I get other metadata: album cover, description, artists photo... 
and for movies, artists, description, trailers, a lot of metadata and related info and resources

but for music, I cannot get the lyrics, I have more than 100 albums and I don't know why nothing seems to have lyrics

I am not even sure I am checking in the right place, but when I play a song, on the /web/#/queue path
there is a button with "lyrics" tooltip which opens a page with "no lyrics found", for every song I try

is there any howto or guide about how one can correctly setup this feature?
is there any particular log I could check to understand if something is broken?

what should I check?

Thanks for any hint.

Is there any guide on ho to debug what is not working?

I have LrcLib Lyrics active (version 3.0.0.0) on jellyfin 10.11.8, since at least a month, but I cannot get any lyric whatsoever

what could I do to debug what is not working?

Thanks!
