Sample ClientId and ClientSecret shown in the below screen can be used for the demo purpose and can later be replaced in the code with newly obtained ClientId and ClientSecret.

File - DemoModel.cs

public Demo()

    {

        ClientId = "4dp5b7gRqk";

        ClientSecret = "fa3a5b16753d09b24bb44243605a4a98";
