I just started exploring URL parameters on survey 123. My goal is to be able to prepopulate the form using an existing record. I have been following the below three posts. However, I am very new to this and got stuck in locating the global id of the survey record that I just submitted.
First, take a peek at the fields for the hosted feature layer by opening the item detail page > Data > Fields. Click the 'Display Name' header if you have a lot and would like to sort alphabetically. Do you see GlobalID there? If so, you're on the right track: open up ArcGIS Pro and add the the layer (Add Data > My Content). From there, you should be able to see all hidden attributes, including GlobalID.
