Heyo - we at idealo successfully built an integration in next.js with pure SSR 👍 and are wondering how we can now do the tracking callback to track the "experiment viewed" event? According to https://docs.growthbook.io/lib/react#pure-ssr we don't really have access to the GrowthBook instance in the browser, and there doesn't seem to be a tracking option on the server instance. How would we solve this? cc: @adventurous-dream-15065
