Robotics Studio / Runtime version compatibility with Pega platform 8.5.1

Hi Everyone,

Has someone came across any article which talks about the compatibility of Robotic Studio / Runtime versions with Pega platform 8.5.1 ?
Specifically we are looking for Robot manager application in 8.5.1.

One of the pre-reqs for RM 8.5.1 is that you use Studio/Runtime 19.1.64 or greater.
