Recovering Apple Music playlists and saved songs after resubscribing

I used to have an Apple Music subscription with my current Apple ID. Later, my subscription ended for a while. I recently resubscribed to Apple Music, but now I can’t find any of my old playlists or my saved songs.

I’m using the same Apple ID as before, and I already turned on Sync Library in the Music settings, but nothing has appeared.

Is there any way to recover my old playlists or music library? Or are they permanently deleted if my subscription was inactive for some time?

Thanks in advance for your help!
