GUI trial version location for Linux

I must be missing something. I downloaded duplicacy_linux_x64_2.0.9. According to the Guide: “The first time you run Duplicacy, it will ask you to activate the license or start a fully functional 30-day trial period” (followed by a picture of the GUI).

When I run the downloaded all I get is the CLI help output with no GUI. How do I access the GUI for the trial period?

Thanks.

The GUI for Linux hasn’t been released yet. ETA is 2 months, see my previous thread
