Update existing Eventbridge Rule to include a new target using CloudFormation script

I have tried to add the EventBridge rule in both applications but it throws an error saying that the resource already exists.

You have to first import your existing EB rule into CloudFormation stack before you can modify it. Alternatively, you can develop a custom resource which can modify the rule without importing.
