I want to be prevented from downloading specific apps

Hi there all, bit of an unusual question I know, but I want to be completely blocked from downloading specific apps.

I know what you are going to say.......use screen time....content restrictions. That’s all good and well and I can see this working for most people, however, I find myself entering my passcode and then lifting the restrictions and re-downloading the specific apps I want to move away from (as they aren’t healthy for me) hence the need for me to have no admin rights to this function, as I’ve built up an addictive behaviour to using the specific apps.

I’ve had a look for third party apps which may help also, alas not being able to find any.

I would really appreciate any comments you may have. Take care.
