I have been able to make all the key features in red work with no issues.  My only issue is the 4th feature and bullet point below in green that I cannot get to work.  Please help!

• Screen pop-ups for calls: Receive screen pop-ups for incoming and outgoing calls to see instantly who is calling you or being called. The pop-ups that appear in Zoho provide detailed information and contextual access to the historical interactions with the contact.
• Automatic call logs: All incoming and outgoing call activities are logged automatically inside the Zoho platform.
• Click to dial: Call your customers and leads directly from your Zoho account with a single click.
• Call recordings: Access call recordings directly from the Zoho call logs. If a call has been recorded, the option to play back the call will appear.
