firestore access denied

[joseph7h]

FIREBASE_WARNING: set at /Messages/-LMZ61mv4YBnYxUqH-y9 failed: permission_denied.

Can you please show your firestore rules so I can correct mine? Details below.

service cloud.firestore {
match /databases/{database}/documents {
match /Messages/-LMZ61mv4YBnYxUqH-y9 {
allow read, write: if true;
}
}
}

Oops, just found I need to change the security access rules for the realtime db, not the firestore db.
Everything works now.

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