To do:

• Add in subscription, container app environment and container app to the view (needs to be tested with the re run work)

Great work, my nitpick UI feedback is that the checklist should also be centered underneath the Generating Copilot Response heading.

And then a potential bigger improvement would be to have the items be more descriptive, rather than a single word like "Registry"

This looks really slick - my only nit is maybe move the "Generating..." message and step progress list vertically up a little bit more

I made some changes to the view so it now has a placeholder for when no items have been selected which looks like this:

After copilot has picked items they will populate below which looks like this:

Let me know if there is anything else we shoudl change about the UI.

I need to release this tools PR for the tests to pass btw.
