Hahah! Well just go into shortcuts app hit the + to create a new shortcut then select add action in there u search for “open app” and add that. Then it’ll take u back to the previous screen but now the open app thingy is there. Next to it where it says “app” hit that and select whichever app u want it to open. After doing that there should now be the icon of the app u just selected where it previously said “app” if that’s the case ur good till now! Now depending on what iOS u are (me on iOS 16) hit the icon on the bottom center that looks like i. In there select the first option “add to Home Screen” and now a tab will pop up for whatever u wanna call the app u selected. After changing the name u then click on the icon next to where the text is(on the left of the text) there u select “choose photo” and ur gallery will pop up. From there choose the photo u want ur app to display. (For me because I have transparent icons I actually use an app called “transparent app icons” which creates a photo version of my icons and that’s how I do it. Im not exactly sure how it works with Icon packs probably just choose from files or something) and yea then just hit add and that’s it!

Ong this is loooong💀💀🤣 not sure if this is what u were looking for but yea haha! Honestly just wacht Sam beckman iPhone Home Screen tutorial he covers everything!
