Think though loading submitted data back into from for read and updates

We can do this in the left panel of the Canva editor. Display a list of submissions. We will probably need a new end-point for it though. We will also probably need to set-up opensearch to easily do it since the Github api would be quite slow. Actually we might be able to get away without opensearch and quickly just get the medtadata like file name and id. Although it would also be cool to have a search as well.
