Description of changes:

Hi Team updated the src/pages/gen1/[platform]/build-a-backend/storage/list/index.mdx file for the section

import { list } from 'aws-amplify/storage';

const PAGE_SIZE = 20;
let nextToken = undefined;
//...
const loadNextPage = async () => {
  let response = await list({
    path: 'public/photos/',
    // Alternatively, path: ({identityId}) => `protected/${identityId}/photos/`
    pageSize: PAGE_SIZE,
    nextToken: nextToken
    }
  });
  if (response.nextToken) {
    nextToken = response.nextToken;
  } else {
    nextToken = undefined;
  }
  // render list items from response.items
};

to

import { list } from 'aws-amplify/storage';

const PAGE_SIZE = 20;
let nextToken = undefined;
//...
const loadNextPage = async () => {
  let response = await list({
    path: 'public/photos/',
    // Alternatively, path: ({identityId}) => `protected/${identityId}/photos/`
    options: {
      pageSize: PAGE_SIZE,
      nextToken: nextToken
    }
    }
  });
  if (response.nextToken) {
    nextToken = response.nextToken;
  } else {
    nextToken = undefined;
  }
  // render list items from response.items
};

Added the options block to ensure correct passing of pageSize and nextToken, as existing code, does not allow pagination. (tested at my end).
