Mapping Dynamics 365 Marketing Form Submissions to Custom Tables with Power Automate

Marketing forms in Dynamics 365 are great for creating and updating contact and/or lead records, but not much else. The documented way to handle form submissions beyond lead or contact is to build a classic workflow but that in itself is very restrictive. By moving the automation into a Power Automate flow it opens up many more doors in terms of generation submission reports, notifications and sophisticated record manipulation that cannot be achieved with classic workflows alone.
