Group users in Firebase RTDB - qt

Question

I am using Firebase in my Qt app for Authentication and Realtime Database features, when users register they need to be assigned into the selected groups then departments of that group. Each group will have admin(s), who can access the entire group database, but the users will only access their department.
Below is my code for my registration form which assigns certain user values, how would i go about grouping the users in the database with additional options on my registration form?
onUserRegistered: {
indicator.stopAnimating()
console.debug("User login " + success + " - " + message)
if(success) {
loginDialog.title = "Success!"
firebaseDb.setUserValue("Firstname", firstname.text)
firebaseDb.setUserValue("Surname", surname.text)
} else {
loginDialog.title = "An Issue occured!"
}
loginDialog.text = message
loginbutton.visible = true
registerCheckbox.visible = true
loginDialog.open()
}
I would like my database to be laid out as below, if this is appropriate for use? Multiple location groups with users within to access thier part of the database!
{
"groups" : {
"Colchester" : {
},
"Ipswich" : {
},
"CanaryWharf" : {
"Departments" : {
"Admin" : {
"members" : {
"user1" : true
}
},
"Assistant" : {
"members" : {
"user2" : true
}
},
"Reception" : {
"members" : {
"user3" : true,
"user1" : true
}
},
"Stylist" : {
"members" : {
"user4" : true
}
},
"Technician" : {
"members" : {
"user5" : true
}
}
}
}
}

Without access to the Firebase Cloud Firestore collections, detailed in the link;
Google Firebase Cloud Firestore Collections
I achieved the result of grouping of my users by the following code, if anyone still wants to add an improved version please do, but for now this works as intended for me:
App {
id: app
property var groupName
property var subGroupName
//these values are assigned when my user logs in from user values
//set in firebase on registration
firebaseDb.getUserValue("group", {
}, function(success, key, value) {
if(success){
groupName = value
console.log("GROUPNAME LOG: " + groupName)}})
}
//I then use these values across my app when storing data in the database
//an example of which is an AppButton elsewhere in my app
AppButton {
id: saveButton
onClicked: {
userData = ({"date": calendar.selectedDate, "name": userName +" "+ userSurname, "details": dayCycle.text, "status": "pending"})
var time = new Date().getTime()
firebaseDb.setValue("groups" + "/" + groupName + "/" + subGroupName + "/" + time, userData)
}
}
