While I'm using my laptop, occasionally when my sister or mom are using their phone it shows up on the bottom bar of my laptop. For example, I was on my laptop, and my sister was texting a friend. The "messages" tab would pop up on the left of my "finder" which is the left-most app on my bar. Is there any way to turn this off, as I don't really need it popping up every time they use an app.
