How to permanently disable SharePlay pop-up on iPhone 14?

Every time I open my iPhone 14, I get the little screen that says SharePlay with (my husband's name) Tap To Open. I do not want to see this every...single...time! I have gone to FaceTime and turned off SharePlay. I have even turned off FaceTime, but this little screen keeps popping up. It does disappear when I go the main screen with all the app icons. A similar thing happened after I listened to a Podcast. Even closing all the PodCast apps that little screen kept popping up when I opened my phone. Maybe different issue?
