I have created the code via the Chat Button design, but am unable to add it to the current Communities page. Community Builder does not allow anything be added in, and Site.com does not allow the template to be edited (as it mentions the page is a Lightning template.) Lightning Components can be built, but do not allow for this sort of scripting. How does something scripted get added via Community Builder or Site.com Studio?
