I'd like the ability to create a new Slack channel from within a Jira Service Desk (or Software) issue.  Specifically I'm hoping to automate this action based on the setting of a custom field.  For example, when a JSD issue's custom field, Severity, is set to Sev1 or Sev2, then create a new Slack channel whose name is that of the issue's key (e.g., SERVICE-13).  From that point forward, the Slack channel and the JSD issue should be linked with updates going bi-directionally.
