[Vuejs]-How do I open a browserAction popup, from within a pageAction popup?

I encountered a similar issue because i had to check async if a specific url was already opened in any tab (browser.tabs.query) in order to naviagte to that tab or open the popup. The problem is after the async call the callback isnt an input handler anymore.

Solution:
set the popup to the browser action and make a script (has to be a separat file). Here you can make async calls and window.close() if something else should happen.
