Unable to reduce form's detail size

[John Sh]

This is best explained in pictures, see below.
I have a simple form with two buttons.
I would like the form to encompass the buttons but not spread out over the page.
The screen shots represent my latest attempts to correct this problem.
I am running Access 2016 on windows 11.
This is what I would like

This is what I get, no matter how I try.

This is what I set up.

By extending the boundaries of the detail window, the background area increases but nothing will reduce it below what is shown in the second image.

And these are the settings. I have tried with popup and modal on, and off.
