Ways to search and open a catalog.
Opening Through Content Studio
With Content Studio opened, search for the catalog name on the search bar, and with the catalog selected, click on the three dots on Actions column and select See on Authoring Hub.
This will open another window with your catalog on Authoring Hub.
An even faster way is to click on the arrow next to the catalog version.
Note: The link generated for your version can be shared.
Search by Catalog name
On the first page of Authoring Hub you can type on search bar for the name of catalog. This way of searching will show all available versions within the catalog.
Search by Version number
Searching for the catalog name plus the version number will result in only the desired version.
Search by Version ID
This ID code you can find on Test Browser inside Test Hub.
Searching for the code will have the same result as searching for the version. To do this, you must use the # symbol at the beginning.
