Find the owner of a Microsoft Form

Here's a hack to determine who created (and is therefore the owner of) a Microsoft Form:

1) Grab the ID of the form:

https://forms.office.com/pages/responsepage.aspx?id=mHcFBexHuEeJJeYuEg8GOReFjaXIXp5Gn24tRTWqhexUNUw2RDSVY1QkwxV040REZSRy4u&route=shorturl

2)  Append the ID to this url:

https://forms.office.com/Pages/DesignPage.aspx?origin=shell#FormId=<Form ID>

and go to the url.  You should see an error like this:

3)  View the source of that page, and search for /users/, and you'll see a url like this:

https://forms.office.com/formapi/api/05057798-47ec-47b8-8925-e62e120f0639/users/a58d8517-5ec8-469e-9f6e-2d435aa908ec

The ID of the user is highlighted.

4)  Go to Azure Portal and do a search for the User ID.  The user should show up in the results.
