I'm trying to add a custom variable to the "Embedded Chat" labels, but I don't understand how the {0} variable works, when I enter the chat it returns the first name plus the first letter of the last name, I want to try to modify it and not show me the last name.
I'm looking for some information but I can't find anything about this {0}, which is supposed to be Custom Labels, but I still don't know how to modify or reassign the value.
