[Inline Frame component for web] How to insert addtional iframe attributes?

The Inline Frame component for web is a great widget. It allows you to either display your content in an iframe (via the src property) or you can inject your own HTML in the srcdoc;
For instance one could use the following HTML with srcdoc component property to create an iframe with the additional allow and style attributes:

"<iframe src=\"https://glitch-me\" allow=\"autoplay; encrypted-media *;\" style=\"width: 100%; height: 100vh;\"></iframe>"

But this result in having the above frame embedded in the parent frame created by the Inline Frame component.
So the question is whether there is a way to add additional attributes (beyond src) to the default Inline Frame component’s iframe?
