Yeah, OP should take this as a opportunity to work on assignment design and course policies for the next time. There have been plenty of times where students did something that I viewed or suspected as dishonest but didn't report them for it because I hadn't designed my assignments well or didn't have a clear policy against it.

I went to a hipster restaurant about a decade ago where they served fries with a shot glass full of chocolate milk shake on the side for dunking. It was really tasty ngl

Except french fries
