How to reference an object during CSV External System Import?

[Alvin Adams]

I have a custom asset object field with an object schema and objects created in JSM (cloud). I am migrating new issues from another system using the External System Import using a CSV file format. I cannot find documentation on how to format the data within the CSV column so that when imported, it will reference the correct object in the asset object custom field. I have attempted to use the key or summary of the object in the column, but neither have worked.
