ID3v2 tags mapped to the Abridged and Explicit metadata fields?

[vmurcia]

Are there any ID3v2 tags (frames) which Audiobookshelf is able to parse and map to the Abridged and Explicit metadata fields for an audiobook when scanning its metadata?

I’ve tried setting the user-defined frame TXXX=ITUNESADVISORY=1, which seems pretty common to indicate that an audio track is explicit, but with no luck.

PS: I use Mp3tag to tag my audiobook MP3 files, by the way.
