# What this PR does - Refactor alert receive channel lookup so it is easier to follow - Remove the additional lookup that was taking place for alert receive channels that belong to a deleted organization, these can be treated as deleted for usage purposes even though the alert receive channel itself does not have `deleted_at` populated - Organizations that have been moved will still need to be looked up everytime. This is not optimized in favor of not maintaining a cache of Organizations. These are not frequent requests and can be optimized later if necessary. ## Which issue(s) this PR closes <!-- *Note*: if you have more than one GitHub issue that this PR closes, be sure to preface each issue link with a [closing keyword](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/using-keywords-in-issues-and-pull-requests#linking-a-pull-request-to-an-issue). This ensures that the issue(s) are auto-closed once the PR has been merged. --> ## Checklist - [x] Unit, integration, and e2e (if applicable) tests updated - [x] Documentation added (or `pr:no public docs` PR label added if not required) - [x] Added the relevant release notes label (see labels prefixed w/ `release:`). These labels dictate how your PR will show up in the autogenerated release notes.
