How Device Simulator?

I read (Device Simulator | Unity Documentation) that Unity 2020.3 includes the Device Simulator but in the Package Manager there is no trace of the Device Simulator. How do I activate it?

Since it’s a (Preview) package, you will need to enable “Show preview packages” under the “Advanced” dropdown in the Package Manager for it to show up.

Thank you

he Device Simulator is now part of the Editor and is accessible from the Game window.
