no-user-gesture-required, user-gesture-required,

Optional customCustom headers for requests sent by the window.
Optional defaultCenters the window in the primary monitor. This option overrides defaultLeft and defaultTop. When saveWindowState is true,
this value will be ignored for subsequent launches in favor of the cached value.

Optional ignoreIgnores the cached state of the window.
Defaults the opposite value of saveWindowState to maintain backwards compatibility.
Optional max-1
