Fill Screen as Default - Photoshop Elements 2020

I recently installed Photoshop Elements 2020.  When I open a new file, the image is in the "Fit Screen" mode - left justified on my screen, leaving 2/3 of the screen empty.  How do I make the default "Full Screen" so that when I open an image, the image occupies the entire screen, with the exception of the Tool Box and the Panel Bar.  I was able to do this in Photoshop Elements 2018.  I know how to make the change when the image is open, but looking to save a step so that it opens that way I want to see it on my screen.

thank you
