autodesk forge – APS Design Automation – Open Revit Cloud Models

I am trying to follow this Blog Post to adapt Design Automation to support access to Revit Cloud Models

My question is how to adapt commandLine to not include rvtFile, since it will be opened by inputJson info (projectGuid/modelGuid). Simply suppress it from the command and from parameters list? Is the data body bellow correct?

{
            "id": "UpdateParametersActivity",
            "commandLine": [ "$(engine.path)\\\\revitcoreconsole.exe /al \"$(appbundles[DA_UpdateParameters].path)\"" ],
            "parameters": {
              "inputJson": { 
                  "verb": "get",
                  "description":"input json", 
                  "localName":"params.json",
                  "ondemand": false, 
                  "required" :false, 
                  "zip": false 
              }
            },
            "engine": "Autodesk.Revit+2022",
            "appbundles": [ "ME_BimViewer_DES.DA_UpdateParameters+test" ],
            "description": "Update Parameters from Revit file."
    }
