Jenkins Pipeline Script equivalent for encoding, returnStatus, returnStdout, label?

If you review the Jenkins Pipeline optional parameters. How would that look like in the Actions Workflow?
The examples in the Migration Workflow do not cover this.

Example Jenkins Pipeline snippet

    returnStdout: true, 
    script: '''

        $WarningPreference = 'Continue'
    label: "warning-label", 
    returnStatus: true,
    encoding: "UTF-8",

Maybe you can try using the PowerShell options to see if it can work:
