I'd suggest looking into Activators to stream pipeline failures to alerts. You can get pretty granular with rules, and it supports both emails and teams messages as actions. I think these are relatively new, so might not have been available at the time this was submitted.
Here's the MS link for the documentation:
https://learn.microsoft.com/en-us/fabric/real-time-intelligence/data-activator/activator-introduction
The activators will give you direct access to things like the workspace name, with nothing more than a click.
But, just so you are aware, it is also possible to use sempy.fabric to programmatically identify workspace names and objects. You shouldn't store a static list which would need to be maintained.
