Accessing Authentication URL with a Telephony Extension

Accessing Authentication URL with a Telephony Extension

Hi everyone, I've been able to get a fair amount of progress done on integrating zoho's OAuth process with an application that I've been developing. This application is displayed in a teleophony extension that I've been developing through Zoho, but I've run in to a bit of a snag

To get the refresh_token in the initial oauth tango, I need to get the code with prompt=consent in the URL, which causes the user to need to press an 'accept' button on  https://accounts.zoho.com/oauth/v2/auth. This would work great, however the Telephony Extension will not allow me to access an outside webpage that isn't the one defined in the connected app. Is there a way to allow the page to access the authentication page?
