When someone books an appointment, the resulting sales opportunity now includes the visitor's language, country, and website browsing history. This helps sales teams better prepare for meetings with more context about the prospect's interests.

Bridge the gap between the web visitors and the lead created when they book a
 demo so that we link all data from A to Z.

When opportunities are created from an appointment:
- add the language and the country to the opportunity
- link the visitor to the opportunity so that pages browsed by the user are
associated with the opportunity (which is useful to prepare the meeting)
