Vk, how to automatically delete users who left the conversation?

Question

Social media

Hello, I would like to know how I can make it so that I can automatically delete users who have left the conversation (on the Vkontakte social network). Without third-party resources, bots, on your own, from your account. Tell me what commands and where to enter so that it works. It's just that some people can do it, but I just don't understand how and with what help. I need it very much. Answer only to the point please. Many thanks in advance for the correct answer.
PS: I know about the VK method, but it takes a long time to kick through it.
