I saw on some FB group an extra feature on comment, up/down arrow icon(in addition to classic 'like'/'j'aime' icon) that open a way to say if the comment is relevant or not for the group.
I would like to add this cool feature on my group but I'm unable to find how to do that?
After some search I finally found that this kind of feature is a test driven by Facebook itself. So I Imagine as simple user/admin we have no way to activate this feature today.
