Go to the Campaigns tab -> Select the campaign you want to modify -> Go to the category ‘Tools’.
Under ‘WebTabs’ you can click on ‘More settings’ or enable the WebTabs feature to add a WebTab URL. This allows you to open a browser tab within the chat interface, while you are chatting with visitors. It grants you the opportunity to look for information more efficiently while supporting the visitor.
Make sure to save when you finished adding one or more links.
