how to detect selenium/webdriver browsing on my site

Question

Does anyone know how to detect selenium/webdriver browsing on my site?

I don't want to block them, just detect them.

I saw this question: Can a website detect when you are using selenium with chromedriver?

But trying all of these on latest version didn't seem to work.

Any body knows anything else?

P.S. please don't leave answers/comments of "dont block"/"you are looking in the wrong place" - I am fully aware of what I'm asking and what will be the business logic to use it.

-- EDIT --

Things I have tested from the link above:

detecting cdc_asdjflasutopfhvcZLmcfl_ key on elements, mostly on window and document but some other elements we have across the entire site.
Searching for window.navigator.webdriver always returns undefined instead of true (tested on both chrome and firefox although only firefox said to support it)
tested the script from this answer: https://stackoverflow.com/a/45814390/1593987

All tests were done using latest selenium, browsers (firefox and chrome), and latest webdriver plugins. for now only on windows, but will probably test ubuntu as well.

I mean to know it is running from selenium/webdriver, don't even need to separate just know about it — Eyal H, Oct 11 '17 at 10:07
"But trying all of these on latest version didn't seem to work." What have you tested for example? — Alexey R., Oct 11 '17 at 10:11
Hi, do you found any solution, how to detect latest version of Silenium? — Serhii Didanov, Nov 23 '17 at 13:15
So far, no. There are a few methods to catch headless browsing, but they weren't effective with selenium — Eyal H, Nov 24 '17 at 13:20

In recent versions of Selenium WebDriver it's handled on a spec level.

There is a read-only JS property - navigator.webdriver which is true in case webdriver is used to control browser.

Checked with Chrome v73 - returns true.
