Chat trigger and eMail registration in chat

Chat trigger and eMail registration in chat

We have configured our web-embed to force registration of e-mail and name from users. This works fine when the user opens the chat window. However we have also included a trigger that pops up the chat window automatically after 2 min. on the users side. However in this case the system does not force the user to enter his e-mail / name. This means that we have no record of who was on the chat. How can this be fixed?
