The conditions I'm talking about are these two:
- If they have issues with no story points assigned for the following sprint
- If the sum of all the story points assigned is bigger to a specified number
I have found some notifications available, these are the ones attached via the photo. But these dont seem to solve my issues. 
If there is no way to get these alerts via Slack, I'd also be greatful if i could get that info through other means, like via the Slack app.
Thanks
