@RaavanSuraj If you have control over the development server, it would be best to have a local service that monitors the jobs and then leverage a logic app that can send out the email notification. You could leverage the Graph SDK directly as well if preferred.
If you don't have control over the development server, then it would depend on the task scheduler library used. If it exposes a REST API, then you can create a custom connector that can leverage the on-premises data gateway.
