Selenium Grid integration!

Hi Team,

I was searching for documentation regarding Selenium Grid integration with Test Project.
My User case here is
We have selenium grid already deployed to AWS Cloud, and want to use the same selenium grid endpoint for my TestProject Execution.
I could not find anywhere how to integrate it from UI itself. I have Browserstack and Saucelab integrated to my account that is working fine for me.

Please guide me how i can run my job in a cloud based selenium grid without installing testproject agent into the AWS selenium grid install (However i have agent installed in my mac mini)

Thanks

Wish to know the same one.
