@heindrichpaul thanks for your contribution. However I'm afraid we cannot merge this PR. The parameters you want to change to "Optional" are "Required" in some scenarios.
But you can check the newest version 0.6.0 of the module, which was merged today with the #4764. It introduces a support for kind: 'Direct'. When you choose Direct, the dataSources property will become optional.

You can an usage example here (Example 6: Send data to Azure Monitor Logs with Logs ingestion API)
