How to create a private tab in Google Chrome?

Question

Google Chrome

You probably thought that I was completely crazy, but no. I want a quick solution to create a private tab , not a window, but a tab in the Google Chrome browser. Those. so that the private tab is among the regular tabs, and not in a separate window!
I have to test the site, it's very inconvenient when a new window opens in private mode. Opera seems to have what I'm looking for in Chrome, but I'm not ready to jump into another browser for this feature.
Maybe someone has an extension that solves the problem? Searched. Have not found.
Thank you!
