@IanWyszynski is going to document how to build & deploy without the need to publish the npm package. I believe the rough steps are:

1. in firestore-bigquery-export/firestore-bigquery-change-tracker:

npm run build

2. in firestore-bigquery-export/package.json:

change the "@firebaseextensions/firestore-bigquery-change-tracker" dependency to:

"@firebaseextensions/firestore-bigquery-change-tracker": "file:./firestore-bigquery-change-tracker",

3. in firestore-bigquery-export/package.json:

npm run build

and then deploy
