Getting errors when screen sharing from an iframe

Description

If you are running your web application inside an iframe, you will receive the following error message when trying to perform screen-share:

Failed to execute 'getDisplayMedia' on 'MediaDevices': Access to the feature 'display-capture' is disallowed by permission policy 

This happens due to a permission policy that was added to all major browsers which explicitly prevents screen share from an application running inside an iframe. Further details about the policy is available at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Feature-Policy.
