I want to allow read and write but not delete existing nodes.
these are the rules I have but is still allowing to delete (update)

```
"messages_test": {
    ".read": "true",
    ".write": "true",
    "$message": {
        ".write": "false",
    }
},

```

this is how I´m removing the node (succesffuly, but i should get permission denied instead)

```
    firebase.database().ref('messages_test').child(id).remove()
        .catch(error => console.log(error.message));

```

thanks for your help
