# What this PR does
Introduces a new class,
`apps.grafana_plugin.ui_url_builder.UIURLBuilder`, which is responsible
for... building UI URLs (😄). The class mainly does two things:
- it will decide if the URL should point to `grafana-oncall-app` or
`grafana-irm-app` based on the value of
`organization.is_grafana_irm_enabled` (**NOTE**: this value isn't yet
being set + defaults to `False`; logic for setting this value will be
done in a subsequent PR)
- Adds `enum`s, `OnCallPage` and `IncidentPage` to DRYify hardcoded UI
URLs (in case we decide to change these slightly in the near future)
