How do I change the chat’s greeting, colors and look?

Use the Chatbot studio. Settings are on the left in tabs, and on the right is your real site with the chat drawn from your changes as you make them.

Setup covers the assistant name, greeting, suggested questions, when it opens, which pages it shows on and what visitors see after hours. Program sets its personality, your instructions, goals, what details to collect, hand-off to your team, topics to avoid and canned answers. Design covers the chat button (style, label, position), a photo or logo, colors, corners, font and an optional nudge. It always says it’s an AI assistant.

Your draft saves as you go, and visitors see nothing until you tap Publish to site. Your last 10 published versions can be restored from Publish.
