I can't find how to create with Aura a Gif image with a transparent background, though I can view and save existing Gif images without loosing their transparent color. I compared in Aura the different properties of the images with and without a transparent color and I can't find a difference.
Does someone know ?

In Aura, most file types with an alpha require you to set the Project window background display mode to None, but GIF seems to be an exception ... perhaps something to do with it being a register color format.

In any case, make sure you have set File>Export>Alpha to an alpha mode (PreMult seems to work.)
 
Indeed, Gifs with transparent background seem to be in PreMultiply mode, though it doesn't seem to be enough to define the transparent color.
