How to get access to UIApplication from dockable panel to import dwg in current document?

[ShapeForm]

Hi, I'm trying to make an extension with dockable panel. I use it to enter parameters with file and to send them to server. Then i want to import file that came from server into current document. For now I am able to just save it in some folder. Is it actually possible to import it by i dont know like pushing another button on dockable panel? As i understood my dock panel doesn't have access to UIApplication, i tried some solutions i was able to find, but none of them actually worked( Maybe anyone knows a working method??
