Issue with Control Add-in in AL extension

[rajprince0]

I'm getting this follow Error, I was trying to use pingpong Addin in my Extension

Microsoft.Dynamics.Nav.Client.PingPong.PingPongAddIn;PublicKeyToken=31bf3856ad364e35, The page contains a control add-in that is not permitted. Contact your system administrator.

Here is my below code declaration of dotnet

dotnet
{
assembly("Microsoft.Dynamics.Nav.Client.PingPong")
{
type("Microsoft.Dynamics.Nav.Client.PingPong.PingPongAddIn";PingPongAddIn)
{
IsControlAddIn = true;
}
}
}

and here is my Addin Page.

page 50148 PingPongAddin
{
// version RG

PageType = CardPart;
UsageCategory = Lists;
Caption = 'PingPong';

layout
{
    area(content)
    {
        usercontrol(PingPongControl; PingPongAddin)
        {
            trigger Pong()
            begin
                Message('Pong received.');
            end;

            trigger AddInReady()
            begin
                Message('Ready');
            end;

        }
    }
}

actions
{
}

}
