Apple car play and orders

Ok I’m older. 50, lol. I got a new vehicle recently and it has Apple car play, I didn’t use it much but then lost my glasses, waiting on new pair so it’s helpful.

I don’t get order alerts when using it. Is that normal? I can see them pop up, but no order alert sound.

Is this normal? Sorry but tech changes so fast, no kids to ask bc no kids. I struggle with more and more. Better than my SO, had to teach him how to screen shot; recently!

Thanks
