Is there a safe instagram secret viewer for parents?

My 13-year-old has been acting secretive about Instagram and I’m trying to keep an eye out for unsafe messages without turning it into a huge fight. I know there are apps and “viewer” sites out there, but a lot of them seem sketchy or require logging in. Is there any legit, safe way for a parent to view activity (even just DMs) without risking scams or getting their account locked?
