## Problem to Solve
Existing Snippet capabilities do not allow for embedding of private snippets, limiting snippet usability to public only.
## Proposal
Refactor permission and visibility of published snippets so that if a private snippet is publish only those with viewable access can in fact view. This iteration will allow users to better use their established snippets in a more functional way, increasing operational efficiency, and enhance the snippets experience/usage.
