- start commandprompt as admin

- type: python hub_patcher.py

- optionally you can give hub root folder: python hub_patcher.py c:\Program Files\Unity Hub\

- it unpacks app.asar file into C:\Program Files\Unity Hub\resources\app\

- app.asar is renamed as app.asar.bak

- next time hub runs, it uses the unpacked "app\" folder, instead of "app.asar"

- so you can modify anything inside app\ folder, this script modifies app\build\renderer\index.html template to add custom CSS styles (for hiding those columns)
