Declared in the header. cxg parses @references and then discards it, and nothing at scan time reads it, so this is the only place the links a template cites are surfaced.

To see what the copy on your machine says about itself, and to confirm it is installed at all:

Terminal window
cxg template info jupyter-unauth-rce

The id it prints is the one to pass anywhere a template is selected. See cxg template for the rest of the subcommand, Scan a target for running a scan, and A match is not a finding for how to read what comes back.
