Feature request: Notifications after deployment

Being able to have auto-deployment through Github actions is great for Azure Static WebApps, but in a project lifecycle, projet's team needs to be notified that a deployment occurred and is finished:

- When pushing to the default branch, all the team needs to know when the deployment is finished without the need to go to Github Actions page.
- When a developer pushes in his branch and requests for QA to test before merging - when are they both aware the deployment is finished and, even more important, how to get notified of the generated URL? They may have access to Github action, they definitely don't have access to the Azure Static WebApps resource in the Azure portal.

I would advise two notifications:
- In Github, being able to have the direct access to the deployment status and the deployment URL

- The first notification content should be visible in Slack / Microsoft Teams, allowing the team to know which checks/deployments have started/are finished with a direct link to the generated web URL.

I'm available on Twitter (felixsportelli) if you need any more details or if you need my teams to give you more insights on how they work.
