Write data from node-red to firestore

Hello I am trying to connect to firebase firestore (not the real-time database).
I can read my collection and document but I cannot write to it.
The msg.firestore property is mentioned in the documentation but I don't get the settins right.
Does anyone here have experience with the settings?
A second question:
What is the difference between the nodes "node-red-contrib-cloud-firestore 2.1.1" and
“Node-red-contrib-firestore 1.0.2”
