In Jira Service Management, when a customer submits an email request they shortly after receive an email that looks like this:

My question is; how can I edit the contents of this email, an preferably also change the language.
Usually one can find these email templates under Project Settings ➜ Customer notifications but not for this particular email, which is strange... 🤔
There is also an email that says something along the lines of "Just confirming that we got your request. We're on it." Would also like to change that.
