We have written an electron app. It shows notifications (Win10). Once the app was spamming with a lot of notifications so I switched them off from the notification tile.
I wanted to enable them back. So I went to notification settings and I could not find my app in the list.
PS: We are using electron Notification module and we are also calling app.setAppUserModelId("OurAppName")
This is a semi-known issue where electron applications are simply missing from Windows Notifications Center.
Try changing
app.setAppserModelId("yourAppName");
To
app.on('ready', () => app.setAppUserModelId("Your.AppName"));
I had the same issue recently and this did the trick for me, I found the solution here: https://github.com/Automattic/simplenote-electron/pull/2483
In other iterations of similar issues, there is a workaround to enable notifications again which can be found here: https://github.com/electron/electron/issues/24330#issuecomment-650546142
For Electron you can find the event 'ready' here: https://www.electronjs.org/docs/api/app#event-ready
