Trying to get this setup on Mac, help would be appreciated using ItelliJ IDEA

[JCrew7384]

I am assuming that this bot still works and isn't blacklisted by Resy... But I am trying to get everything running on my Mac. I had to install git, home-brew, sbt, etc. I downloaded the code. I opened the project in the IDE. On the step that says look for the small sbt in the top right and click the arrows to download libraries, I don't even see that. I don't want to keep progressing through the setup if that doesn't even exist yet. Can someone assist?
