You cannot add anything to the database if you're not authorized. You can do one of the following:

Either set this to your rules tab in firebase console:

{
"rules": {
".read": true,
".write": true
}
}

Or you must create an authentication first (try with email/pass) and create user with

createUserWithEmailAndPassword(email, password)

and then sign in with:

signInWithEmailAndPassword(email, password)

and you need to enable sign-in with email/pass in your console as well.

And then you can write data to your database.
