I have a Teams/Power App using Dataverse.
I use a form to add a Request, and in the OnSuccess property of the form I am trying to trigger Power Automate, but I cant figure out how to get the right value to pass to Power Automate.
The first step of the flow is "Get a Row by ID" and it asks for the rows "globally unique identifier (GUID)".

In my Dataverse Table, it says the unique identifier is called "Requests". This is an auto-generated field, I did not add it.

So what I cant figure out is how get this field in Power Apps so that I can pass it through to Power Automate
// Send Notification Email
'ANZMPT-NewRequestNotification'.Run("me@mydomain.com",WHAT DO I PUT HERE?);
I'm not super knowledgeable about data types/field types etc so this a big challenge for me.
I wondered if I had to send the whole record, so I tried First(Filter(Requests,'Request ID' = FormNewRequest.LastSubmit.'Request ID');
Something like FormNewRequest.LastSubmit gives me an error straight away (red squiggly line under code)
Something like FormNewRequest.LastSubmit.crdcb_requestid is not 'available'
