The chat widget opens based on its own display rules and triggers, but there is no way to make it open in response to a visitor clicking a specific button elsewhere on the page.
Admins should be able to configure a webpage button to trigger the chat widget to open, so visitors can initiate a chat by clicking a call-to-action rather than finding the widget on their own.
Passive widget discovery leaves engagement to chance. Button-triggered chat lets teams place high-converting CTAs anywhere on the page, driving more intentional chat initiations from visitors who are already engaged.
