title: Way to get timestamp of last activity for all Slack users
body: <p>I am building a Python script which retrieves a set of information for all Slack users of the organization that I work. Currently, I was asked by the stakeholders to retrieve the last time that our organization's users were active on Slack. I came across the <a href="https://api.slack.com/methods/users.getPresence" rel="nofollow noreferrer">users.getPresence</a> method but this can only return a timestamp for the owner of the token. Has anybody worked on that before? Thanks.</p>
