Hello, I implemented the integration of visitors 
through jwt, so my customers click on a button on 
my website and then they are directed to the 
zendesk support screen, there is only one problem,
 on this screen there is the chat and I noticed
 that the "name" fields and "e-mail" although 
already filled in, they can be edited.

how can I do so that the user cannot edit 
these fields in the pre-chat?
