正在尝试向<TabbedForm>的<Toolbar>添加下一步按钮，以便滚动选项卡

import { TabbedForm, Toolbar, SaveButton, Button } from 'react-admin';
import ChevronRightIcon from '@material-ui/icons/ChevronRight';
import { makeStyles } from '@material-ui/core/styles';

const useStyles = makeStyles(theme => ({
  nextButton: {
    marginLeft: theme.spacing(1),
  },
}));

const CustomToolbar = props => {
  const classes = useStyles();

  const handleNext = () => {
    // 执行下一步操作
  };

  return (
    <Toolbar {...props}>
      <SaveButton />
      <Button
        label="下一步"
        onClick={handleNext}
        className={classes.nextButton}
      >
        <ChevronRightIcon />
      </Button>
    </Toolbar>
  );
};

<TabbedForm toolbar={<CustomToolbar />} {...otherProps}>
  {/* 表单字段 */}
</TabbedForm>
