This default window menu is provided by the system and on some platforms provides functionality for setting or changing privileged state on the window, such as moving it between workspaces or displays, or toggling the always-on-top property.
On platforms or desktops where this is unsupported, this function does nothing.
This function is available since SDL 3.0.0.
