launchMenuModal function
Toggles the visibility of the menu modal.
This function calls updateIsMenuModalVisible with the negated value of
isMenuModalVisible to toggle the modal's visibility.
Example:
final options = LaunchMenuModalOptions(
  updateIsMenuModalVisible: (isVisible) => print("Menu modal visibility: $isVisible"),
  isMenuModalVisible: false,
);
launchMenuModal(options);
// This will open the modal if it's currently closed, or close it if it's open.
Implementation
void launchMenuModal(LaunchMenuModalOptions options) {
  options.updateIsMenuModalVisible(!options.isMenuModalVisible);
}
