Laptops are stored in the git repository. If you click the "git Repository" icon on the notebook recording page, it will take you to the Cloud Repo page in the Google Cloud Dev Console. Select the datalab_main branch from the drop-down list and you will see the files ready for commit. After committing, other users can click Refresh on the same page in the Dev Console (Source | Browse in the left navigation bar) and they will see the changes and new laptops.
Another option is to download the laptop as an .ipynb file and share it this way.
