Saba K. hmm I guess its not possible. I can't really think of any ways at the moment because I'm assuming you also can't use the "custom code embed" element either, right?
Saba K., you should be able to put all your script in slater and then, copy the slater script on the code of your site, not in an embed (you should never add GSAp script on embed by the way, always on the page or site code)
