Problem with autostart

I recntly got back to usig aero and am loving the new interface. I set my action to start automatically and saved as a .real file but it does not start automaticaly. I do not know if it is because i have the Aero app on my phone and it is opening in there but I have to hit preview. is there a way I can test it to see how those that I share it with will view it? I created the experience in the Aero app on a Mac laptop running Monterrey 12.7.2. I used my own 3D animated cartoon Rabbit which I animated in Mixamo. I am playing it on an updated    pro Max and it opens automatically in the app. I do not want my users to have to click to play  to see the danciing Easter Bunny.
