New notebook, how do I get my Minecraft back?

I bought a new notebook because my old one broke.

I had previously bought Minecraft Windows 10 edition. Now I don't have it anymore. I downloaded the trial version again. I signed in to my Microsoft account, but it still didn't work. I also have an X-Box life account, which I also signed in with, but again didn't work.

Maybe one of you knows how I can get it back? I had spent a lot of money on it and I don't want to buy it again.

You would have to register your Microsoft account in the Microsoft Store and go to "My Games" and there you should be able to download it
