How to create new record specifying ID?

I am trying to set a table in Firebase that holds some information about the user ID from Firebase. Basically linking my internal corprate ID to the Firebase Auth user ID.

For the life of me I cannot figure out how to make a record in firebase while specifying the ID. Any help?

Any help here? Still unable to get this working with the “create record” item

Firebase connector does not yet provide a method for setting your own IDs when creating documents. I answered how to do this with HTTP request flow function in the link here
