HI there,
I am working on integrating Salesforce with Amazon Connect.
I have followed the exact instruction as per salesforce and amazon documentation @https://trailhead.salesforce.com/en/content/learn/projects/build-an-amazon-connect-integration?trail_id=innovate-with-alexa-and-amazon-web-services
While testing, being in Service Console, I can see Phone utility at the bottom, see attached screen1. But when I click it, it opens up in new pop-up window but shows error : "URL No Longer Exists", look at screen2 image.

I re-run complete steps. Couldn't find issue, may be I overlooked some aspects, any help on the same please ?
