I'm currently developing an interactive message menu that prompts users to select another user in their Slack group. Following this guide I am able to prompt the user to select one user from the entire list of users in the group.
I would like to know if it's possible to limit the size of the list to n specific users? If not, is it possible to set the order of users or at least shuffle them randomly? I should be able to do this using data_source: external but would like to know if this can be achieved more elegantly using data_source: users.
No, if you want to show only a subset of users you have two options.
