Does Mini Program's customer service function need to develop its own interface?

I was just looking at Mini Program"s customer service message document, but someone said that don"t worry about this piece, just throw a button open-type="contact". In the debugging tool test, you found that the chat window did not come out. Do you have to develop your own server interface?


No, just use button. If you are not useful in development tools, it is recommended to test it on a real machine.
