How do I launch edtor on Ubuntu?

Running Ubuntu 20.04

I hit a block while following the installation instructions:

  1. Download the .zip file containing the version of Unreal Engine that you need.
  2. Unzip the contents of the .zip to your desired installation directory.
  3. Run Engine/Binaries/Linux/UnrealEditor from the Terminal to launch Unreal Engine.

Zip file downloaded Ok, unzipped it, but at step 5, there is no such file, or any program files that seem relevant
