The actual name of the icon is `transmission`, so you would have to rename the file to that and add `id="transmission"` to the group. Since this is a desktop theme icon, you would also have to add an invisible 22x22 rectangle to the group. However, even after doing all that myself, I can't get this icon to work. I'm not sure why.
