Unable to change Background Color for pushed SettingCustomView

[RizwanaDesai]

SettingPage(title: "Integrations") {
                     SettingCustomView {
                                        IntegrationsSettingView()
                      }
}

I'm navigating User to Custom settings view where i want to change background color for that View including navigation area, but unable to set background color for entire screen. Attached is the screen shot for reference.

Any help would be greatly appreciated.
