        This playbook is used to handle the results from the "Microsoft 365 Defender - Threat Hunting Generic" playbook inside a phishing incident. It will perform the following actions:
        1) Set the relevant incident fields based on the results, such as "Clicked URLs", "Malicious URL Viewed", and "Malicious URL Clicked".
        2) In case the relevant playbook inputs were configured, it will create new incidents for each email returned in the results. First, it will try to retrieve the original emails' files and then it will create an incident for each retrieved email.
        3) Link the newly created incidents to the main originating incident.

        Note that this playbook should only be used inside a phishing incident and not as a main playbook.
