How do I change my screen time passcode if the ‘forgot passcode?’ does not show up on screen?

When I tried to change my screen time passcode, I watched videos and almost every single one said to click on the ‘forgot passcode’ on the screen when pressing change my passcode. However when I followed all the steps there was nothing. No blue writing saying ‘forgot passcode’. And I also know that my phone should be updated and it is; IOS 15.4.1 which it says up to date as well. So Idk what to do at this point 🧍🏽‍♀️, hope someone can answer this for me.
