To open the new tab when clicked on url from the application

Question

Hi All,
 
Could you please guide me on how to approach the below scenario:
 
Application initial screen is a grid view ,when clicked on one item in the grid view, new page gets opened as tab, in that new page there is an option to copy the link of that tab as https://localhost/ExApp.Client/ExApp.Client.application?tablink=12348671-1458-487D4-D84FA-48861dqdecad"
which can be copied to any of the client machines and from there they can open the app as click once app
 
How can I implement the code where when clicked on the url, if application is already opened then he should be able to open the url with new tab in the already opened application, as of now when url is clicked we need to close this instance and open a new application but we want to have a new tab in the already opened application which should not allow the application to close.
 
Thanks and Regards,
Ruth
