I want to convert my purchased music to MP3 but I can't find my purchased music in iTunes anymore

I have purchased music through the ITunes Store and in the past have been able to convert to MP3. Recently, when I logged in, I was notified that the ITunes Store is now for audiobooks and podcasts and all music is in Apple Music.

I want to convert my purchased music to MP3.

I do have an apple music subscription for streaming but I am looking to convert only the files I've purchased. I can't figure out how to do that now, it appears this is a new change.

None of my music shows up in Itunes anymore.
