How to pass the message text for the VKontakte dialogue in the URL?

Hello!
I can't find a list of all the parameters that VK supports in the URL. I accidentally stumbled upon the fact that you can add &msgid=1 and go to the first message in the conversation. Googled, but did not find a list of all such parameters. You need to create a link in which the text of the message will be transmitted. For example, something like &message=Hello, so that when you go to the message field, it will already say "Hi". Tell)
