Opens the webpage at "url" in an iFrame (on the right side of the screen) or close that iFrame. `allowApi` allows the webpage to use the "IFrame API" and execute script (it is equivalent to putting the `openWebsiteAllowApi` property in the map). `allowPolicy` grants additional access rights to the iFrame.
