Filter a Gallery in Canvas Apps on the Status Reason field (or any other OptionSet in CDS)

So this post is out of pure frustration that this information seems to be really hard to find (for me anyway) for what seemed like a basic requirement. I wanted to load a Gallery of information in a Canvas App based on the status reason within the Common Data Service. This field is often used in model-driven apps, including Dynamics 365 so being able to filter on this is pretty necessary for companion Canvas based apps.
