Hi Ankit,
Thank you for your question,
If you wanted to check & troubleshoot whether your extension application was opened inside the Symphony Desktop Client or Symphony Web Client (accessed via web browser) - you will need to use the 'Developer Tools' on each of the clients.
For the Symphony Desktop Client - you will need to click on the following selections from the top naviagation pane.
'Help' --> 'Troubleshooting' --> 'Toggle Developer Tools'
For the Symphony Web Client (accessed by web browser) - you will need to open the 'Developer Tools' from the web browser such as Chrome.
This will open the Developer Tools in a new window - you can click on the 'Network' tab & ensure the 'Console' view is shown on the bottom section.
You can clear the existing logs on the Network & Console sections before proceeding to opening the extension application from where you are loading it from.
You will be able to see if whehter the extension application appears on the Developer Tools on either the Symphony Desktop Client or Web Client. You will find the log entry that appears with the reference to the extension application too to ensure it is the right application.
I hope this helps but should you have any further questions or feedback - please let us know.
Sorry for not giving more detail. I need to check it programatically.
