Hi @Dannwasere,
At this time, Crowd Play is an invite only beta mode that players had to apply for back in 2020. I am unsure if Stadia is currently taking any more applicants at this time, I couldn't find the form online when I just looked. Keep your eyes peeled to this Community and we will be sure to let you know when Crowd Play will have launched for everyone!
