We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Configure a Sentry denylist
Looks like we can configure a `denylist` on `EventScrubber` when calling `sentry_sdk.init`: https://docs.sentry.io/platforms/python/data-management/sensitive-data/

Another more general approach to modifying events is to configure a `before_send` function: https://docs.sentry.io/platforms/python/configuration/filtering/
