Hi Robert,
That is correct "POI" or Point of Interest is not a road. Likely you will want to reverse geocode that Lat/long and see what you get back for a location. You can try both reverse address & reverse cross street search and see if they work for you. https://learn.microsoft.com/en-us/azure/azure-maps/how-to-search-for-address
