Hello @cassiocardoso, I came across your GitHub repository while setting up a similar script to install my apps.
I wanted to share with you a way to install Mac app from Mac App Store automatically. You can use mas cli.

brew cask install mas

I also have a question : What is the purpose of the "link cask apps to Alfred" line 63

Little correction in the GitHub desktop cask code.

Right now it's Just GitHub.

The code will be

brew cask install --appdir="/Applications" github
