Is it possible from my IPhone to delete an App from ICloud?

Long story, but I need to start my usage from scratch.
The adjustments I need are maxed out in the cloud.

It doesn’t work by deleting the App from my phone and calling it back up.

Google says: Link

To permanently delete apps from iCloud, tap Show All under APPS USING ICLOUD from the iCloud menu and toggle off the switch next to any app you wish to remove.

No good.
The App does not show up in the list.

Here is what I found

Most of my ICloud storage is photos

Thanks guys
