Broken fan socket off the board/ how much glue?

Hello, I accidentally broke it while changing the thermal paste. I tried to test if the fan was still working while I was holding everything down with my finger on the exact location and it was fine (hurrah for me.) I did read that you could try to glue it back on the forum but there was no extra information.

My questions are:

1) Can I use any kind of glue or does it have to be of a specific brand?

2) How much exactly can I apply? I am quite clumsy with glue. If you see my picture, I put a dot in color. Can I expand over it a little bit over that area, to make sure it is going to hold on tight?

Thank your for your answers and have a lovely indoor repairing week-end!
