### Enhancement description

Currently, I'm using Localstack to test locally a lambda function that takes s3`ObjectRestore:Completed` notifications as inputs and it would be really great to have support for these events.

I know that right now as a workaround I can invoke the lambda function manually using a payload with the same shape that s3 uses, but it's better to have the process run as close as it would run in AWS.

Thanks for creating and maintaining localstack, it's really great!

### 🧑‍💻 Implementation

Not sure, but happy to help if you can give me some pointers.
