Repair iPhone 8 Plus screen, while I was gone my nephew tried to help!

Ok so I was replacing a screen on an iPhone 8 Plus and I know the drill always know where the screws go so they go back in the correct place. But… I took a break while I had to go to work and while I was gone my nephew thought he could help with no experience at all. Not to mention that I believe some of my screws are missing. I’m already ordering a replacement set of all the screws that go in the phone but now I need a diagram breakdown of which screw go where with the size and position of all the screws. If there is anyone out there that has a link to such a diagram or even an appropriate YouTube video that goes into that much detail it would be greatly appreciated.

thanks to all who respond.
