ITLibMediaItemLyricsContentRating availability in Music app

Not really sure if this post belongs here, but it pertains to the iTunesLibrary Framework.

While looking through the iTunesLibrary framework, I came across the subject constant. However, I do not know how to set this within the Music app.

Is this a legacy feature of iTunes before Apple switched to Music with Catalina?

I looked through the preferences for Music and I do not see where to turn this feature on, nor is it available as a display column in Music while viewing songs as a list.

I have been managing my music by appending (Clean) for a non-explicit version of a song with explicit lyrics, or (Explicit) if a non-explicit version is not available.

It would be nice to not have to do this if this feature can be turned on in the Music app.
