Adding new user to group message

Is is possible to add a user to an group message that is already in place? In slack if you @mention someone in a group message it invites them to the group message.

Hi @abalter,

Thanks for your question!

You can add a new user to your group message by clicking on the “v” to the right of the group message name in the center channel. This will, however, create a new conversation and the updated group will appear in the left-hand-side panel under “Direct Messages”.

You can read about group messaging here

Does this help?
