Help fixing a key that fell off

Macbook pro 2017. My E key fell off and I can't seem to get it to click back in to place. The bottom two hooks latch on fine, but the top two clamps won't click in to the white clip underneath the key. Whenever I press on the bottom half of the key, the top half lifts off of the keyboard and the E letter isn't activated. Trying to figure out if it's the key, the white clip underneath, or if I'm just doing it wrong. I'll attach pictures of the pieces here. Looking for what pieces I'd need to order to replace it, as well as a quick guide on how to do it, since all the apple stores here are closed.
