Sounds pretty simple if you just have patience and do what the directions tell you.
I'll probably make a really tiny square with masking/painters tape around the area it came off along with the grid that was unharmed with the mixed compound, and I'll also put a dab on the tab itself and sit it on the window for a few minutes, then take a hair dryer to it for a little bit and after that let it sit overnight.
