I’m not sure how this module works but to get your local project in the portal you can follow the guide here: https://docs.mendix.com/refguide/upload-to-version-control-dialog
This will provide you with a mendix app id.
Not sure if the module works locally, but you can get your app ID alos with the MprTool.exe program in the mendix install dir/modeler.
Open the program, open the mpr file of your project and select the project in the left hand explorer and in the bottom pane you’ll see your $ID. Not sure if the works for the module and uploading this to the could might be the required way forward.
