Connect IntelliJ to Your Script Root Jira Software

[Thomas Höfler]

I am going through this tutorial: https://scriptrunner.adaptavist.com/latest/jira/DevEnvironment.html and I am wondering, if anybody knows how to do that: 

"Connect IntelliJ to Your Script Root

You can connect your locally running IntelliJ IDEA directly to a test instance of your Atlassian application (Jira, Confluence, Bitbucket Server, or Bamboo). This will let you edit the files in your server’s script roots directly with all the benefits of IntelliJ."

I successfully set up my local dev enviroment for Scriptrunner, but have no clue how to connect Intellij to our Jira TEST instance. 

Any help is appreciated.
