In using the rule OG new content notification (admin/config/workflow/rules/reaction/manage/rules_og_new_content) for a site using Organic groups. However, I'd like add in the name (and URL) of the parent group. However, I'm not seeing these options in the tokens ("replacement values").
The Content Type in question has the field
og_group_ref for which I'm trying to target.
What I've tried so far (update):
On a dev instance, as per Pierre's recommendation below, I've added the following 'fetch entity' to the rule.
