      allow
      
    
    
The allow property of the HTMLIFrameElement interface indicates
the
Permissions Policy
specified for this <iframe> element. The policy defines what features
are available to the <iframe> element (for example, access to the
microphone, camera, battery, web-share, etc.) based on the origin
of the request.
The Permissions Policy specified by the allow attribute implements a
further restriction on top of the policy specified in the  header. It
doesn't replace it.
See <iframe>'s Permissions Policy
syntax for more
details.
It reflects the allow attribute of the iframe element.
