Deleting photos

[RRHMJ23]

I was trying to delete photos, I clicked a photo and pressed delete, a message comes up that says " photos doesn't have access to delete items on your SD card. Go to gallery app to continue delete.”. I don't see the gallery app on the phone. What am I doing wrong my other phones I was about to delete any photo no matter where they're stored.

Make sure you assign the correct permissions to whatever app you are attempting to use by going to settings/apps
