is Firebase delete user data extension capable to delete all documents in deleted user subcollections?

Question

I wanna try Firebase extension delete user data.

Say in Firestore I have path like this

users/{uid}/inbox/{messageID}

and also

users/{uid}/posts/{postID}

My question is....

Is Firebase extension delete user data capable to delete all user message documents, and all users posts documents in Firestore?

from the documentation in here , it seems it can only delete the document that has the same uid in the root main collection only for Firestore. am I right?

From the same documentation you linked:

Configuration Parameters:

...

Cloud Firestore delete mode: (Only applicable if you use the Cloud Firestore paths parameter.) How do you want to delete Cloud Firestore documents? To also delete documents in subcollections, set this parameter to recursive .

When you install the extension, you should see a prompt for this parameter and answer recursive :

  - param: FIRESTORE_DELETE_MODE
    label: Cloud Firestore delete mode
