Open the .zip file of the texture pack

Go to path "/assets/minecraft/textures/gui/sprites/hud" and open the crosshair.png.mcmeta file.

We're interested in what's inside the frame brackets [].
0 is the first frame and 10 the last one, you can see this in crosshair.png
{"index": 0,"time": 12} refers to a pause at frame 0 with the time you want.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, is the frame order that the animation will be in.
You can add or remove frames depending on the animation and pauses you want.
Don't forget that everything must be followed by a comma “,” as seen in the image
