    So I am using the Draw over native ui feature with my main camera's alpha set to 0 to get a transparent application. Now, I want to use post processing effects like colour grading, bloom, etc to alter the colours and look of the system, kinda like using my application as an overlay. But sadly I can't seem to make it work. That's probably because how post processing works, and even if it's drawing over the system UI, the system is not a part of the app itself. But can I achieve this effect somehow? Like, using some custom full-screen shader to saturate the screen's pixels, or maybe taking a screenshot of the screen and having that image on a canvas and apply post effects to it or something like that. Like is that even possible? I am not experienced with writing shaders. Also I am focusing on Android only. Please help, like I really need help :(
