Usage In Passage Elements

Add a custom token store directly into the Passage elements.

Example custom token store usage in Passage Elements

Create and pass a custom Token Store to handle storing the auth token in localstorage only, overriding the default client-side auth token handling of storing in both localstorage and cookie.
