Context: We are building an app, where we want to add ability to enter fullscreen mode for part of our UI using Fullscreen API. But in order for it to work the appropriate `fullscreen` iframe policy permissions need to be set.
I have checked the ZAF docs and community but didn't find a way to configure iframe policy permissions. Also seems like Zendesk allow lot of permissions by default, but not a fullscreen.
So is it possible to enable it somehow and use fullscreen APIs in embedded apps?
