The visibility of your storyboard is determined by the storyboard "Insert Access." This means that you can use the storyboard ID within its own project. If you would like to insert it somewhere else or use it when creating from storyboard id, you need to change the insert access to either Within account or Public.
Glossary
None - the storyboard is only visible in its own project and can not be shared or reused when copying it.
Within account - everyone in the account can use the storyboard ID.
Public - if you would like to share your storyboard with the rest of the world (or at least to other Storykit accounts).
