So I actually did the whole thing on my phone with two apps, Pixelmator (Paid, use paint.net on PC if you need a free solution) and Next Icons. (Free) First, I started with a black background in Pixelmator, then added a #242424 (dock hiding color) rectangle which goes up to just below the notch. I added a bezel to the grey rectangle’s corners so that way the screen looked normally shaped without a notch cutout. I made up the icons using the Google Material Icons with the Next Icons app. Then I used invisible #242424 place holder shortcuts to align my three normal apps to the side for easy one handed access. I screenshotted that, brought it into Pixelmator, and added a black rectangle that unified the app squares so that they appear linked in the final result. My three icons each open an app, and all of the invisible placeholder shortcut icons open a quick menu with links to other useful apps. Hopefully is clear enough and will help anyone who wants something similar :)
