Does anyone know how do i disable family link on my old phone?

i got this old phone still locked down with parental controls from when i was a kid and cant figure out how to turn them off even after digging around in settings. tried a few things but nothing sticks. anyone got steps that actually work for removing it for good?

Check if you have the Family Link account credentials. If not, you’ll need those to disable it. Without them, removing parental controls is difficult.
