call a function in page_messages

[BedrettinOrtak]

Hi, this is more of a helpful question than a question. I want to convert this interface into a chat program, but I need to write a code block that is constantly waiting while receiving the incoming message, and I need to run the send sendbyfriend function remotely in the chat section, but the chat cannot access this function from the outside in the chat section that has already been created. In the section where I got the message, I need to reach and run this function, how can I do it? can you help me?
