How to configure Rules to send email after new comment to OG members

I know it is possible and very basic, but cannot figure out how to do this.

I have backdrop with OG module, Rules module. I need the site to send an email to every group member after a comment is sent in forums.

I cloned the "OG new content notification" Rule that comes by default (since it works as needed).

Edited the Event to: "after a new comment is saved"

Edited the Condition to: Entity is group content - Parameter: Entity: [comment:node]

And left action as is.

Did not work. Found other comment paramenters, but with numbers 1, 2, 3 which I am not understanding.
