Moderation buttons not working in offcanvas slideout

The chat plugin works fine on a dedicated page: https://kcnr1460.com/chat/, but when used in an offcanvas slide out (https://kcnr1460.com click the icon in the upper left), the moderation buttons don’t show. Sometimes the icon of the three dots will load, but do nothing when clicked. Suggestions?
