What you get
Last page URL on the visitor profile when the widget sends it. A highlight command that draws a short banner on the host page for a few seconds. Visitors stay in control of their browser — this is not co-browse or screen share.
Why switch for this
You do not need a second product to know they are on checkout. Open the thread, send a highlight, keep talking in the same inbox.
Last page URL on the contact tells you they were on /billing or /checkout. Send a highlight from the thread and a banner appears on their page for a few seconds.
