About theme use of designer.exe in pyside6

I hope that when using the "designer.exe" program, I can set its theme color and the default style of controls, rather than having it decided solely based on the system default settings. For example, I am currently using the dark theme in Windows 11, so the "designer.exe" program  also use the dark theme. However, the "designer.exe" program is very uncomfortable to use in the dark theme, as many of the controls are hard to see.
