How can I copy music from my iPhone 8 to my new MacBook Pro?

When my data was transferred from my previous MacBook Pro to the new one, my iTunes music library was on an external drive which had crashed. - so all of it was lost. Whatever was on iCloud was later transferred to my new MacBook Pro; but there's music on my iPhone 8 - from the old iTunes that was not on iCloud and is missing on my new MacBook Pro. How do I add that music back to my new Music app on my new MacBook Pro in addition to what was restored from the cloud during data transfer? Is that doable?
