I'm looking for grad watch dogs legion In the Xbox but can't find what to do?

Hello as some watch dogs fans have heard there's watch dogs legion free to test over the weekend & I'm here in the Xbox Store on the Xbox one but only find it for a fee & who can help me?

In the star screen or when you scroll down there should be a "play with gold for free" tile or something like that.

You can only download it there, not in the store.

However, I didn't even know that this is currently possible on Xbox.

Yes, I did it, I did it on my mobile phone & yes, it's free on all platforms until Monday
