I have tried this, and the extension requires at least 1 provider to be functional:

I struggle to find any provider that is defined by default, and according to the wiki it appears to be a framework rather than a usable extension. For the store to actually be usable, you would need to create another extension that adds a provider. Therefore, I am afraid this cannot be included (unless I am missing something and the extension is actually usable on its own(?), in that case feel free to flag this post and I’ll unlock the discussion)
