Looking for an App-Blocker which can Unblock Offending Apps when Certain Screentime is Achieved

Greetings! I am looking for an app which blocks distracting apps like NewPipe, Infinity and Facebook and unlocks them when the screen time of 1 hours and 30 minutes of a productive app like OneNote is achieved. This should also apply to distracting websites.

I think the screen time of productivity based apps requiring distracting apps to be unlocked is a fantastic way to stay productive and I have not seen any blocking apps implemented this feature.

TIA
