node.js - How do I write/update data to multiple child nodes via Firebase Cloud functions?

Question

I've got a database that looks like this:

I want to reset the Patient_List and Current_Token children to 0 at a particular time (say 12 AM) automatically for all the users in the database.

I went through the Firebase cloud function docs and these projects on gitHub: Deleting nodes and Delete unused user accounts using Cron. Both of the above examples update and change data based on a particular UID i.e update only particular nodes based on the UID passed. I would like to know if it is possible to update values for the above child elements in all the nodes and if so , how would it be done?
