wordpress live chat problem

[aoogod]

Hello technician, when I configure 3cx to my wordpress, there will be a problem of not very good experience when communicating with customers. When a customer establishes a chat with us through the mobile terminal, it opens a new page. When returning or accidentally closing the chat page, the session is also closed. We cannot reply to the problem encountered by the customer, which leads to our user experience. Not good, I hope there is a solution, or the customer opens the chat and does not change the chat window to a new page, so that he can continue to stay on the website
