c# Added Value Listener in MongoDB

I used firebase with c# in my project and it had a on value added listener which listens if any data is added then executes a function based on this

async private void listen()
    {
        EventStreamResponse response = await server.OnAsync("server", Degistiginde);
    }
    private void Degistiginde(object sender, ValueAddedEventArgs args, object context)
    {
        get_Data_from_client_node(args.Data);
    }

is there anything similar in mongodb in c# where I can use to do the same function
