How to publish my lego microgame

Hello everyone, I want to participate to the Lego Microgame, but when I try to upload my game on unity’s website, the tutorial is uploaded instead of the game I’ve created. How can I upload the correct game?

Thanks for your answers.

I believe the correct way to build and upload the game is not through the normal way, but in the top menu you will have a category named something like “Build” or smth like that (just look for it) and it allows you to automatically build and upload at the same time to the website. If you try to do the conventional way it won’t work.

Thanks you for your answer, to publish my work i used the category ,Publish in the top menu, i think this is what you are talking about. So the problem don’t come from here.
