API method for restoring popout back to its origin

[borglin]

Is your feature request related to a problem? Please describe. I want to add a button inside my popout window that mimics the behaviour of closing the browser popup window, but I can't find the right API call that automatically adds it back to its origin, or a best attempt to do so.

Describe the solution you'd like Being able to call something like props.group.api.redockPopout instead of having to figure out where the popout group originated from.
