Ribbon Workbench - RUN DIALOG Smart button In D365

Hi,

I've written a dialog and want to run the same Dialog by clicking on "Run Dialog" button added from Ribbon Workbench to Contact entity.

The Dialog seems to be working properly if i start from "Start Dialog" button available out of the box in the Ribbon but the same Dialog doesn't seem to be working when i Click on "Run Dialog".

Can anyone suggest!
