Custom Button Links in Slack Messages

[hd-deman]

What would you like to see!

Summary: Please add support for custom button links (runbooks, dashboards, logs etc) in Slack messages sent by Grafana OnCall.

Use Case: Currently, I'm working around this limitation by including plain URLs in the message body. While functional, this results in cluttered and unprofessional-looking messages, especially compared to native Slack buttons that are clear and visually distinct.

Proposal: Allow users to define custom buttons with a label and a URL in Slack notifications. This could be added either via the Grafana OnCall UI or as part of the templating system.

Benefits:

Cleaner, more readable Slack alerts

Easier and quicker response actions for on-call engineers

Product Area

Alert Flow & Configuration, Chatops

Anything else to add?

I envision it as an additional raw section with buttons, placed right after the alert description:

Compare it to how messy it looks right now:
