Add an "X" button to top bar of Licensing window

[Bud]

Could an "X" (close) button be added to the top bar of the Licensing window in ArcGIS Pro?

Admittedly, I was distracted/in a rush, but I kept clicking the button in the top bar to close the window. But as the mouseover suggests, that button maximizes the window, it doesn't close it.

While there is a Cancel button at the bottom, I believe the convention is to also have an "X" button in the top bar too, which would be more intuitive. 

ArcGIS Pro 3.0.2 (upgraded today).
