WordPress

Good afternoon, there was a need for a chat between 2 users when they perform specific actions. When entering the page, there was a button to contact the user in the chat. A window opened, and there are only 2 of these users.

Answer 1

Is that what you call private messages?
Chat between 2 users?
The WP-Recall plugin can do this. It has an add-on (included in the basic version) RCL Chat - allows both private messages and many global chats in general. See the description of the add-on here https://codeseller.ru/products/rcl-chat/ well, the plugin itself with it is available in the official WP repository
