For example, let's say that you have a string containing any number of Slack user ids (i.e.
<@W012A3CDE>), and you need to extract out just the user ids.
Here is the string you are starting with:
string = "*Message*: _Great work on that <@U03SPLX0X> , <@U93AEJ9C2> <@U6YB7VBFU> and <@U6Z3YF92P> nice job! _"
string.scan(/<@[^>]*>/) #=> ["<@U03SPLX0X>", "<@U93AEJ9C2>", "<@U6YB7VBFU>", "<@U6Z3YF92P>"]
