Teach me like I am 5, please Text messages don't chime or pop up

I have a 23 toyota and pixel 6. I have tried, in vain to get my text messages to make a chime, or show up on the screen. Even if I have the message page on the display in the car, no notification is given, I simply see the message. I think I have the phone message app (google) set to allow all notifications, but clearly I must not.

If someone can walk be through this I would greatly appreciate it.
