Inputting layer data from map into survey field

[EnvironmentalCompliance]

I've seen guidance on this previously, but I cannot seem to find it anymore.  

I have a survey which people are registering their property for a program.  I want them to be able to click on their parcel (polygon) from a map and have data from that polygon be populated into a survey123 field.  

How would this be possible?

You can use a launch URL like this sending over whatever field you want.

arcgis-survey123://?itemID=9b40228b32204f87aa63ee7d08299b17&field:PlotID={PlotID}

if web form it is https://survey123.arcgis.com/share/ID  instead

See here https://doc.arcgis.com/en/survey123/get-started/integratewithotherapps.htm  for the details.
