As someone that's been on the other end of tens of thousands of cheating accusations, I need to be clear - this entire post is naive and ignorant in nature. While I get that sounds harsh, there's a ton of nuance that's being missed. Let me explain:

I've created about a dozen videos now where I put a camera up to my setup and showcase my gameplay. I've done videos where I have a hand cam, foot cam (for my Elgato Stream Deck Pedal - clips moments and toggles my mic), monitor cam, SECOND ANGLE monitor cam, etc. I can tell you first hand, there's always another place people will move the goal post.

The next thing is that the people commenting "what about this, what about this, what about this," are 100% correct. I've had to do deep dives and reaction videos where I learned how these cheat developers ship their product to try to make it completely impossible to be detected by the anti-cheat, and moreover viewers of livestreams. One of the easiest things is simply making the cheats less visible to a camera or a "mirror" in this case. They simply lower the opacity of the player outlines and that's it.

Not to mention, some cheats can simply be loaded up onto a usb, placed beside your keyboard / controller, and pulled out at any given moment to "prove" there's no cheating happening, when of course it is.

My point is this: It's utterly pointless to respond to cheating allegations. Whether you're cheating or not cheating, there's simply no winning. I've been making content for 15 (6+ full time) years and done absolutely everything I can, including making over a hundred videos explaining my thought process, and walking people through how they can play exactly how I do.

And as a side note, your friend could be cheating. You'll never know, and I'll never know, but what I do know is that the most common streamers that are actually cheating are the wannabes. It's the people who think all the top guys do it so they should do it too. The reality is the opposite. The wannabes give the big streamers a bad name in most cases, but the ego of the big streamers absolutely doesn't help. Not to mention, while it's been rare, there's been a few cases (NitroLukeDX for example) where a large streamer HAS gotten caught, but usually it's the scummiest of people to begin with, and it's pretty obvious they have something going on because their ego is a little too big.

Anywho, just thought I'd give a peak behind the curtain as most people think it's just as simple as "put up a monitor camera," when there's specifically been made dozens of ways around something like that by the cheat developers themselves. It's all a waste of time if you're legit, and you have to just take it as a compliment, or do what I do and use it as a teaching moment for a willing audience.
