An animated gif should just run by itself without you doing anything. 
Just show or hide it as needed. The default setting for animated gifs is 
to run them in a loop at their saved framerate.

Alternately, there are pre-made examples in the icon library, they're 
also animated gifs. Create a button and set its icon to one of those. 
Then just show or hide the button as needed.

Rev's pre-made examples are a fixed size. If you want to adjust that, I 
think the easiest way would be to make an animated gif that is as wide 
as the maximum you'd ever need, import it, make it invisible, and set a 
button to use the image as its icon. Then reize the button to be the 
length you want to display. An icon that is wider than a button will be 
truncated on both sides, so your button width will determine how much of 
the image shows.
