How to put in the F Keys

Hello everyone,

I spilled coffee all over my new mbp, I removed everything and cleaned all the parts in the inside with isopropyl alcohol and my mbp still works :))

Now I tried to clean my keys and I started with 'F3' key. But I can't really get it back in. I put it back in but it doesn't feel like the other buttons It barely moves when I press it. Could someone explain me, maybe with pictures how to properly put in the Function keys? I already searched the internet for videos but I can't find anything for the new butterfly keys. I only found a picture of the white butterfly mechanism and I'm sure my butterfly mechanism is placed in properly but still the key doesn't properly work

Best Regards
