JIRA Webhooks for my own Glip (not a conversation) - how can I alert people when a JIRA task is assigned?

I am looking into creating JIRA webhooks for everyone in our organization to alert them in Glip when a JIRA task is assigned to them. It works great when it is part of a conversation, but that doesn't make sense since its multiple people. Right now, if I assign it to someone in the organization, the webhook works, it is just not alerting anyone. There is no desktop alert and there are no little unread messages noticed on the icon or my name. Does anyone have an idea how I could get this to happen?
