Is there a way to access the new tab created from a Redirect?

[Kris_Doyle]

I'm using something similar to the following snippet to redirect the user to a new tab:

redirect.dispatch(Redirect.Action.ADMIN_SECTION, {
  section: {
    name: Redirect.ResourceType.Product,
    resource: {
      id: id
    }
  },
  newContext: true
});

This currently opens a new browser tab and loads the product with the specified ID. What I really need is to be able to grab a handle to the new tab so that I can detect if it has been closed.

I was using vanilla JS for this before (which was a little hacky), but I'd like to use AppBridge. The problem I'm running into is that I can't figure out a way to get access to that new tab. I tried subscribing to the dispatch event, but that doesn't actually work at all for some reason.

In any case, does anyone have any thoughts on how I could access that new window (tab) so I can detect if/when it's closed?
