# What this PR does
- Improve performance of the specific `GET /users` and `GET /teams`
calls that're made by the Add Responders dropdown in the UI
- Add `GET /team/{teamId}` internal API route (needed by Grafana
Incident team for their Add Responders changes)
- Some UI improvements to the Add Responders popup (loading state +
pre-fetch users and teams when the drawer is opened)
- Re-enable django-admin only if `settings.SILK_PROFILER_ENABLED ==
True` (need to be able to log into django admin to auth to silk routes)
