How can I disable or customize the chat window on my website?

Hello

I have inherited a shopify site from another developer. Am trying to figure my way out.

The site is designduality.studio.

I can see a chat window on the home page. How does one disable / customize it?

Thank you

Found that this is the quick replies feature.

Disabled it by Inbox → Appearance → Online Store Visiblity

Thanks.
