Problems with family share

My mother got the family share from Apple plus and a sharing the iCloud space with me. I’m having a bit of difficulty sharing iTunes music library.

I’m trying to share her purchased music on her iTunes to my iTunes. The family share is all set up. Purchase sharing is enabled and description of above the purchase sharing window says I should be sharing the apps and media, should be the iTunes purchases on my mothers phone? I do have the shared option selected in iTunes to show me the shared music, but nothing is appearing in my iPhone. I can’t figure out if I’m missing a step or not can anybody give me some assistance on one? I’m doing wrong.
