Google Analytics 4 Measurement Protocol doesn’t automatically extract data fields like Device Category, Operating System, or Platform for you. If you want to track these dimensions, you’ll need to manually set them as custom dimensions and include these custom parameters in each HTTP request. For the ‘ua’ query param, GA4 Measurement Protocol does not parse it, so unfortunately, it won’t help to populate the Users by OS table.
