Cannot use material-ui with storybook "Can't resolve '@emotion/react'"

I am using webpack@5 for storybook of my project. The problem is when I use my component in storybook (which uses material-ui components) I get error:

ModuleNotFoundError: Module not found: Error: Can't resolve '@emotion/react' in '/Users/USER/Dev/PROJECT/front/packages/components/node_modules/@mui/styled-engine/GlobalStyles'

I have tried to install this package, add it to addons, add alias for this module to storybook config, install other strange material-ui modules. Nothing works for me, still the same error.

Can you help and suggest what I can try to solve this?

So I found some solution on a page and it works for me:

//main.js
webpackFinal: async (config) => {
    return merge(config, {
      resolve: {
        alias: {
          '@emotion/react': getPackageDir('@emotion/react'),
        },
      },
    });
  },

//main.js
function getPackageDir(filepath) {
  let currDir = path.dirname(require.resolve(filepath));
  while (true) {
    if (fs.existsSync(path.join(currDir, 'package.json'))) {
      return currDir;
    }
    const { dir, root } = path.parse(currDir);
    if (dir === root) {
      throw new Error(`Could not find package.json in the parent directories starting from ${filepath}.`);
    }
    currDir = dir;
  }
}
