is this file meant to replace this? https://github.com/amundsen-io/amundsen/blob/main/frontend/amundsen_application/static/js/components/Alert/index.tsx

I remember reviewing a few small changes recently that seem to have been made in the index.tsx file but not here. not sure if this one just hasn't been updated, and if so should the index file be deleted as part of this PR?

Great work and addition! Do we any documentation on how to configure and use this feature? @B-T-D

I can try to add more documentation at some point. There's a bit of documentation in the form of docstrings in the code currently.

Basically, you will need to have some separate service that is generating these notices. You then configure a concrete notice client that subclasses BaseNoticeClient. That notice client's job is to talk to whatever non-Amundsen service you're getting the notices from, and turn them into Flask responses that are understandable by the endpoint in api/notice/v0.py.
