How to recover missing Share option for downloaded music files on iPhone?

I found some music files on my iPhone 13's music which I would like to copy onto my MacBook however the Airdrop/Share option is missing from them.

I synced these onto my iPhone before my MacBook had its Logic Board replaced but unfortunately my backups of the time do not have these files(long story).

Is there any way I can copy them back onto my MacBook? These are not simple music files bouht from iTunes but copies of edited/remixed tracks I made in Logic ProX and those project files . It would save me hours of work of having to recreate them.
