Is there a way to auto add a group "@" mention to a chatter post? Have a use case for when a specific business group posts, there is a chatter group that should ALWAYS be mentioned and the client wants this auto added so that there is no possibility of the user forgetting and the post gets missed.
I have tried using a Process to call a Flow to add in the "@Group" or "@[Group]" tagging to the body of the FeedItem after it is created or create a new FeedComment with the same tagging, but it just shows up as text and does not "trigger" the group to be called out.
Here is details on the Flow and what happens on the chatter post:
Variable that takes the existing body and adds chatter tags in multiple attempts, using both specific text, reference to variables that hold text or ownerID as is in the example on the help article (https://help.salesforce.com/articleView?id=process_action_post_mention.htm&type=5):
