How to activate Android trial

I downloaded the latest version of Unity and it said:

Free Full Version for Windows with
Unity Pro and Android trials.

I want to get into android development, and would like to see if I can get my game running in the android simulator before investing in hardware and a license.

How can I start my trial of Unity Android?

Install, activate and choose the 30-day Pro trial.

Hi
It’s not work for me. I am usin 3.4.1 and there is no android trial license.
