Hi Team,
By the document Using Existing Themes , set parameter in web-screens.xml for Settings window , then user will can’t change the theme of application.
If the Settings window is opened from help menu, it works as expected.
But if open Settings window through clicking Settings button on side menu, then will cant get expected result.
