Include Zotero entry ID in BibTeX file export?

I would like to know if there is a way to include the Zotero entry ID as a custom field when exporting a collection. (By "Zotero entry ID", I mean the unique eight-character string that follows "https://www.zotero.org/users/user-number/items/" in the URL for a particular Zotero entry. For example, 'XALD6MVT' in this item in my personal collection: https://www.zotero.org/users/3809901/items/XALD6MVT.)

Here is the problem I'm trying to solve. I use Emacs to do all my research, and with the org-ref (https://github.com/jkitchin/org-ref) and helm-BibTeX (https://github.com/tmalsburg/helm-bibtex/) packages I can search for entries in a BibTeX file auto-generated by the Better BibTeX Zotero extension (https://retorque.re/zotero-better-bibtex/) and quickly insert them into any document. With the cursor on an entry so inserted, I can then select from a menu a number of options, such as opening the associated PDF, finding related works on Google Scholar, and copying the associated citation to the clipboard. If the BibTeX file included a field for the Zotero unique ID, I could create an Emacs function that allowed me to add to that menu the convenient option of opening the entry in Zotero.

    With a BBT postscript:

    if (Translator.BetterTeX) reference.add({ name: 'key', value: item.itemKey })

    but the key is only unique to the library, not across library/groups.

    Great, thank you!
