I've written a custom field for Jira, and it uses some DOM manipulation to init the field as an AUI Select2 (https://docs.atlassian.com/aui/latest/docs/auiselect2.html). I would like to use this field in Service Desk, and it seems that the "JIRA" context unfortunately doesn't exist in Service Desk (I get `Uncaught ReferenceError: JIRA is not defined` when loading the js resources).
Ok, not a huge deal, I don't really need the JIRA object, but I was wondering if there a way to programmatically detect my custom field id so I can do the necessary DOM manipulation to get feature parity as in Jira.
