isLoading or isFetching (please don't discuss this point, they're just handfull flags for such generic question). By using these flags we can manually return Loading UI components, but I don't see the way combining tRPC and Suspense react's component. Nor with the loading.tsx server component *.useSuspenseQuery on a page.tsx file and I could detect the loading.tsx content, but it seemed that the query was cached and therefore it no longer appeared after refreshing the page.
