Add polygon by iD URL arguments

[JackNUMBER]

Hello, I'm looking for a documentation about iD URL parameters for GET request. I searched Google and OSM Wiki without result.
My goal is to add a "virtual" polygon on map as boundaries for the contributor (like HOT does with its integrated iD).

eg. https://www.openstreetmap.org/edit?editor=id#map=2/24.1/8.6&comment=#default message&hashtags=#hashOne,#hashTwo has map, hashtags, comment arguments

Thank you

I had the same question and my research shows that HOT tasking-manager provides boundaries as GPX file via gpx URL parameter:
