Retrieving Node URL from Alert

Elastic Observability Metrics
1

I have created simple CPU alert inside Stack Management, with action that send a message to Slack.

I wanted to have the URL to the node causing the alert inside the message.
I found the url inside {{context.action}} variable, which has the format of [View node](https://...).

However Slack does not support this syntax and show above code as it is

It would be nice to be able to get only the url, without the [View node] part.
If there is a way to do that already, I would appreciate the explanation, if not, I suggest creating ticket for that.
