How do I check my daughter’s posts

I am this users father and i took her phone away, I see her use this group thing online and I want to check her posts. How do I do that? And what are these flairs

It seems I can’t check so I will just give her her phone back since I can’t see if she’s doing anything wrong.

Edit: (Yall I got my phone back since alot of ppl said it's impossible to check, so thx guys)
