Configure Laravel project to update and delete json objects

I am using firebase and mysql as the backend. I can insert data to firebase using laravel project. But deleting and updating operations only valid for mysql. I want to make active those features for firebase also. I am using 'Mpociot\Firebase\SyncsWithFirebase' to sync data with firebase. It is perfectly working for insertion only. I need a solution for that guys.
