Navigator window- A way to zoom in workspace, not artboard

Hello, 

first, english is not my first language, so please excuse if I don't use the correkt terms.

I was wondering if there is a way to zoom in the navigator window. I don't intend to zoom in the main window, but just the navigator window. I have things outside the artboard, therefor the navigator window is zoom out alot.

There is an option in the navigator's burger menu, but that isn't super helpfull. 

( I attached a screenshot, not sure if it will be shown in the post)

I appreciate your help

Have a nice day
