GCS: Google Cloud Storage (Lab)
Not able to add allUsers to share files from storage
found solution, add allUsers with Public entity
this video is wrong. You should select Public for Entity not User.
See -> https://cloud.google.com/storage/docs/access-control/making-data-public
Click on Permissions Tab => Add User "allUsers => Select Role: Cloud Storage Legacy = Storage Legacy Object Viewer => Save => Allow Public Access.
