I tried building a macOS app with Electron, but I ran into problems during notarization. I used notarytool to upload my DMG and got status: Invalid. xcrun notarytool log output { "logFormatVersion": 1, "jobId": "680bf475-a5f4-4675-9083-aa755d492b18", "status": "Invalid", "statusSummary":

succeeded, but notarization is failing. I’m a beginner with macOS signing/notarization. Could you please help me figure out what I’m doing wrong and how to fix this? I’d really appreciate any guidance.
