Mango db integration with uipath

I am trying to use Mongodb with uipath for database connectivity.
I have installed the database package,Mongodb driver. provider name as “System.Data.Odbc .And i have created cluster in mongoDB Atlas too. But when I use the connect activity it throws an error that “remotehost address is invalid”.
I don’t know what to do. Also i don’t know what to provide in the server column

I used Invoke Code in C#.
