As a admin I am able to create an unlisted topic and schedule the publishing using the topic timer. This is awesome feature and I would like to allow a specific group of users to do this.
As there no group based permissions it is not possible, isnt it?
Are those Specific Users Moderators or Just casual Users?
on our forum, Moderators can do that and process is just the same as You do it being an admin.
Sure just make that specific group of users, staff 
They are a specific group of users. Not moderators.
as Jeff suggested, add them to staff group
Thanks, iam really new to Discourse :). So there no other way as adding them to moderators. I will try Moderator Extension to get this work.
We’re Discourse not Discord!
