I have been through multiple malware and virus scanners to remove a "app" named CumulonimbusincusPileus. This "app" is "Managed by your organization" and has proven to be undetectable by Defender, Malwarebytes, Zemana, HitmanPro, SpyBot, SuperAntiSpyware, Kapersky, as well as all manner of online scanner tools such as Housecall, ESET, and Norton. I am aware of how it arrived, wrong click and suddenly I'm downloading and installing a browser I said "no" to. Thing is, Zemana was able to remove it from Chrome, but not Edge.

No, its okay, I thought that may be an easy method to find the folder that extension was installed into.
That extension is no longer active in Edge, and it can do no hard, run a full scan with Defender or your preferred anti-virus to ensure there is no malware on your PC

Well, it did something. Edge now detects that it's unwanted, but it does not give me an option to manage the extention, nor does it allow me to delete it.
That extension is now disabled and so can do no harm on your PC.
It can be very hard to find the extension files to delete them
Open File Explorer, then paste this into the Address Bar and press Enter
%LocalAppData%
Do you see any folder in there with a strange name you do not recognize?
If you do, please provide a screenshot of the contents of the folder.
Nothing really out of the ordinary. A few names that I did not recognize turned out to be game saves or something I deliberately installed to remove said extention.
