There are two basic ways to use the Burp Bounty Pro:
1. You can run all profiles against the request insertion points defined in them through an active BurpSuite scan, with the "extension only" library.
2. You can run a Smart Scan based on the Rules. Right button-> Scan with Smart Scan
"Collaborator" status in Dashboard means that you can't know at the moment if there has been success or failed, since the interaction with collaborator can be carried out hours later. This can be seen in the Burp Suite Dashboard.
