How to run Selenium in pre-existing browser?

Question

So, I made a web page on which I have a button that when clicked runs Selenium code (I'm writing in Python). I want my Selenium code to run in this existing, manually opened browser(in which I pre-opened this web page) rather than open new browser window. I already looked through all the similar questions here, but every answer requires opening chrome in debugging mode (which I want to avoid) or doesn't use this manually opened browser but some else. My idea is that there needs to be a way for me to get session id of my existing browser and "give" it to Selenium so it knows where to run. Any ideas, solutions? :)

Answer 1

It's officially not supported.

However, there is some working code which claims to support this:, Also this is in java I am sure you can make in your desire language
