Cisco asa 5520 site to site aws vpn

I have setup multiple site to site vpns, and currently have tested my aws vpns work fwithout issue when i use any other local router, but i cannot for the life of me get my asa 5520 to work with a aws vpn. I read it may not even be possible with that modal? Looking to connect asa to aws and send a successful ping to private network on aws. This is mostly a debuging task. All work will be done via team viewer with me.
