Test this pull request

• The package can be tested by running

  npm i "https://sdk-team-cdn.decentraland.org/@dcl/asset-packs/branch/feat/add-admin-toolkit-smart-item/dcl-asset-packs-2.1.3-13467275373.commit-b93ce86.tgz"

Remember, if new assets are added in the PR, they won't be avaliable on the CDN until it gets merged. So this can be used to test changes on the package's JS or the catalog.json, but won't work to test newly added items.
