Unity3D installed, successfully used and closed. Now how to open it again?

Hello Guys,

I'm running a brand new Centos 7.

I've downloaded a UnityHub file from the Unity website, and installed it.

Through the UnityHub interface I've installed Unity3D.

Installation was complete, I've noticed there were no shortcuts created...

After completed installation I've successfully ran Unity through the UnityHub interface that was still open.

Unity3D Editor worked perfectly with the whole IDE and 3D views and all. Great.

I closed the editor, and UnityHub also closed automatically.

Now I want to use the editor, but where do I find it again?

I've used the standard installation directories for installation.

Here's what I've tried:

In the following directory:

Home/Unity/Hub/Editor/2019.4.4f1/Editor

I find:

BugReporter
libfbxsdk.so
libRL.so
cef_100_percent.pak
libffmpegsumo.so
libtbbmalloc.so.2
cef_200_percent.pak
libfreeimage-3.18.0.so
libtbb.so.2
cef.pak
libispc_texcomp.so
libumbraoptimizer64.so
chrome-sandbox
libOpenCL.so
locales
Data
libOpenCL.so.1
Unity
icudtl.dat
libOpenCL.so.1.0.0
UnityHelper
libcef.so
libOpenImageDenoise.so
Unity_s.debug
libembree.so
libpdf.so

Which one do I open and how? Or is it located elsewhere?

I'd also like to create a desktop shortcut.

Any help would be appreciated.
