For the last couple of months whenever I've tried to use Maps for navigation it's constantly pinged me with a notification telling me that for it to work properly I need to give Google Play Services some extra permissions. This will repeat every minute or so as long as navigation is active (whether you swipe it away or leave it there). Of course navigation works fine, they just want me to enable more data access for it which isn't needed for my uses. In my case this was microphone access, which I don't need as I don't use voice control, and body sensors, which I cannot see the relevance of if I'm not using Google Fit (and should be obviously irrelevant if you are asking for driving instructions, but not necessary even for walking).
Anyway, I got fed up enough to find out exactly what needs to be disabled to shut this up: select the notifications controls for Maps (android 8 and 9 certainly, never used 7 so don't know there), and right at the bottom under "Other" there's a tick box for "Google Play services availability". Untick that and you won't be bothered by nagging messages about permissions that aren't needed in the first place.
