Can I capture notifications that flash too fast to see?

Every once and a while, out of the corner of my eye I see the Ubuntu 20 system I'm using to run my 3D printer flash a notification at the top of the screen, but it always disappears before I can see what it says. Is there an app to record notification history I could run so I could review these things and find out what is going on? I subspect it is a momentary problem with wifi, but can't prove it.
