Bypass cell phone lock Family Link?

I know the question was asked a lot, but still. I have such a strange Android phone from LG. They usually make laptops. I've already tried a lot, e.g. To create a secure folder, but I don't have a Samsung. My main concern is to write messages (don't have a WhatsApp, just a signal). Maybe taking photos, too, but that's about it.

Thanks. My parents will probably notice, right?
