How to make a multilevel condition rules in firebase?

Question

I My rules allow the user to read and write data if the localId, but I want to add a condition with email verification, I found a line of code on the Internet, but I don’t know how to add it correctly:

{
  "rules": {
    ".read": false,
    ".write": false,
    "$localId": {
      ".read": "auth.uid === $localId",
      ".write": "auth.uid === $localId",
    }
  }
}

that is my rules

".read": "auth != null && auth.token.email_verified"

and this is what I found

Answer 1

Include the condition auth.token.email_verified == true for .read and/or .write!

{
  "rules": {
    ".read": false,
    ".write": false,
    "$localId": {
      ".read": "auth != null && auth.uid === $localId && auth.token.email_verified == true",
      ".write": "auth != null && auth.uid === $localId && auth.token.email_verified == true",
    }
  }
}
