Hi @ericnordelo , just following up on this. Would appreciate it if you could take a look at the PR when you have some time. Happy to address any feedback. Thanks!

Hey. Thanks again for taking the time. I will review it it early this week. Thanks for your patience!

Thanks for the feedback! @ericnordelo I understand your point about that approach potentially being redundant. I've updated the implementation and changed the approach based on your comment. Could you please take a look and let me know if I'm heading in the right direction or if there’s anything else I should adjust?

[turkaturki]

Thanks for the clarification! I've reverted is_emitted to its original form.

@ericnordelo Could you kindly check the modified changes.

Hey @turkaturki, thanks for the patience! Note that we still have a couple of issues with the PR, including some tests failing and adding keys to events that don't require them. To be mindful of your time and avoid delaying this feature, I will take this PR and complete it to get it merged as soon as possible, including, of course, your commits. Thanks again for the contribution!
