There is currently no user-friendly way to search for SDoC media, because there is not a SPARQL endpoint like the one for Wikidata. However, there is an option to use the 'haswbstatement' action in the search engine, but this is pretty cumbersome because you need to know property and item ID's. So this will be a visual way to search for SDoC media.
A video of the prototype demoed during the 2020 Hackathon is available on YouTube.
In the process, i'll also create a Vue-based UX library with components that can easily query Wikidata and other Wikimedia projects.
