@MorganMeik These are 2 different integrations that can't be clubbed without a valid AEM license.
Adobe Asset Link extension for Adobe Creative Cloud for enterprise extends the capability to search and browse, sort, preview, upload assets, check out, modify, check-in and view metadata of AEM assets within Creative Cloud applications.
In simple terms, you need Enterprise license and IDs for both creative cloud and AEM.
If users only have access to Workfront - AEM integration, they unfortunately, can't access the creative features related to Indesign or any other CC tool.
Answer to your bonus question - the feature is not available as of now (as per my current understanding and experience).
You might want to reach out to Adobe support to get any info on a future release or raise a feature request here: https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager-ideas/idb-p/adobe-experien...
Hope this clarifies.
