Telephony App not installing correctly

[schmorrison]

I have made an extension using Zoho Developer but cannot get the Telephony icon to appear after I install the app. It works fine in the sandbox but the widget doesn't get retrieved for our production Zoho CRM account.

I followed the instructions here: https://www.zoho.com/developer/help/extensions/embedded-apps/

https://www.zoho.com/developer/help/extensions/embedded-apps/building-a-client-side-app.html

https://www.zoho.com/developer/help/extensions/buildingwidgets.html

Even though the documentations have inconsistencies, I have tried all things that make sense but the telephony icon doesn't appear after installation.

Thanks,
