acitonSheet component click event

  showActionSheet = () => {
    const BUTTONS = ["Operation1", "Operation2", "Operation2", "Delete", "Cancel"];
    ActionSheet.showActionSheetWithOptions({
      options: BUTTONS,
      cancelButtonIndex: BUTTONS.length - 1,
      destructiveButtonIndex: BUTTONS.length - 2,
      message: "I am description, description, description",
      maskClosable: true,
      wrapProps,
    },
    (buttonIndex) => {
      this.setState({ clicked: BUTTONS[buttonIndex] });
    });
  }

Click to pop up the actions panel component, but clicking on the button inside does not take effect. Everything else is normal
