We are using the CRM Cards through CRM Extensions API. So HubSpot sends a request to our webhook, where we have an primaryAction to open a iframe in hubspot.  
Our response:  
**{**  
**“primaryAction”: {**  
**“height”: 800,**  
**“label”: “New Video”,**  
**“type”: “IFRAME”,**  
**“uri”: “[https://app.mailvideo.com/new](https://app.mailvideo.com/new)”,**  
**“width”: 800**  
**},**  
**…**  
**}**  
I believe that HubSpot’s predefined iframe is not allowing display-capture [Permissions-Policy: display-capture directive - HTTP | MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Permissions-Policy/display-capture)

The second pictures throws the following error:  
_DOMException: Failed to execute ‘getDisplayMedia’ on ‘MediaDevices’: Access to the feature “display-capture” is disallowed by permission policy._

Soulution:  
Add display-capture in your iframe allow attribute:

\<iframe allow=“camera; microphone; display-capture” …\>
