How to sync Home Videos on TV app from macOS Catalina 10.15 to iPhone?

Since the update to Mac OS 10.15 (Catalina) split the iTunes app into Music, TV, and Podcasts I can no longer transfer home videos from my Mac to my iPhone. I used to do this by: 1. Adding the home video to iTunes. 2. Dragging it to the iPhone icon that appears when the phone is connected via USB cable, and 3. Using 'sync'. Although the iPhone icon appears at the same place in the TV app, I can no longer drag home videos to it. I also tried right clicking on the iPhone icon and using 'Sync' -- but the home video never syncs onto my iPhone How do you do this transfer now?
