Open overlay on on drag trigger + on drag documentation

Hi,

  1. Is there any more detailed documentation on the on drag trigger apart from general article on prototype triggers (https://help.figma.com/hc/en-us/articles/360040035834-Prototype-triggers)? This trigger seems to have a few condition to work I think (eg. like content expanded over parent component frame … I think at least, etc). Are these conditions documented somewhere?

  2. At the moment I am especially interested in 2 questions concerning this trigger:
    a. Can on drag trigger ever pair with “open an overlay” action on a parent frame?
    b. Can on drag actually ever work out of a component (apart from setting variables, which I have tested, that it can do out of a component)?
