Music that is on iPhone no longer on Macbook after Sequoia 15.3.2

I updated my Macbook to Sequoia 15.3.2 and now, in the Music app, no songs are there. All my songs were there prior to this update. My iPhone still has all my music. How can I get all the songs and playlists from my iPhone to the Macbook and keep them synced? I looked at other Apple Community Support posts but Apple keeps changing the names and locations of tabs, so I don't see the tabs/tick boxes that others are talking about. Does anyone know how to do this in a post 15.3.2 environment?
