Can someone give me help in putting the front grill back to it's place in my A3? It's not firmly on it's place but I can't

It seems it somehow was misplaced while my additional highbeam headlight were installed. They had to do some stuff with the grill while it happened.

I would rather put it back on my own that taking it back to who did the installation.
