I found this article about the subject which is very clear and easy to follow but didn't quite do the trick for me.
I'd like to somehow be notified when I'm tagged on an internal note or when one is created on a ticket I'm following.
How do I go about doing that?
Thank you!

Hi Karina,
Thanks for contacting Zendesk!
If an agent @ mentions you on a ticket, you should be added and notified as a CC. This is providing you have CCing enabled on the account.
If you would like to go down the Trigger route however, you can do so with the conditions in the attached screenshot :)
Make sure the name matches your name in your account.
I hope this helps!
