Moxie Piece not receiving Form Submitted test data

I’ve setup a connection between Moxie and ActivePieces with a Trigger for “Form Submitted”. The setup is all pretty straightforward (thanks to whoever wrote up those steps) but the Piece is missing the option to set the authentication (currently set to None on the Moxie side).

When I go to test the trigger and submit my test Moxie form, ActivePieces isn’t catching the data. Can someone confirm what the Authentication type should be and test that the “Form Submitted” trigger is working as expected?
