@chrissy_portee thank you for your request, and welcome to the community! 
Agree, it would be great to have Snapchat along with other chats we provide, I hope we will be able to think about it in our future updates 
We have this widget idea in our list, by the way: Snapchat Widget - Integrate Snapchat Features to Your Website for Free.
Many thanks for your help, it does mean a lot to us and you’re always welcome to share your thoughts with us here!
