How to get Dynamic Select Value to Use as a CC

I have the following dynamic select dropdown (has more values but excluded them for obvious reasons), I want to be able to use the value instead of the text that is shown. When I use the [staff] shortcode in the mail tab but it is returning the text not the value (in this case would be the email address). Can anyone help with this?

[dynamic_select staff id:staff class:form-control “[email protected]|Test”]

Additional Headers section:
Cc:[staff]
