As I don't fully understand about the issue when you mean " but notebook doesn't format properly to show as it is in the datalab" , when the the datalab instance is created, it adds notebooks to
cloud source repository in the project. As source repositories uses IAM for
access control, you can add IAM to members to grant them permissions to view or update repositories. I would suggest you to check with this
documentation for sharing notebooks in your team. You may also visit this
stackoverflow thread for more information.
