  ///     and `Action` to the modifier's closure. You use this store to power the content in a sheet
  ///     you create that the system displays to the user. If `store`'s state is `nil`-ed out, the
  ///     system dismisses the currently displayed sheet.
  ///   - onDismiss: The closure to execute when dismissing the modal view.
  ///   - content: A closure returning the content of the modal view.
