What adhesive or glue can I use to stick the LCD screen to its base?

Hi,

When replacing the power button of my LG G5 the LCD screen got loose from its base and now it has a 2 to 3 mm gap on the left side. What type of tape, or glue, or adhesive can I use to stick it back? Is the iFix film, item code: IF303-087-1, intended for that? If yes, do I have to remove the entire LCD screen, put the film bellow, and then stick it to its base?

As only one corner of the LCD screen has a gap, I am inclined to use tape of liquid glue to deal with that corner only and not to have to remove the entire thing.

Thanks.
