Hi @jbesw! I'm trying to do this with a Rule with a specific EventBusName, but it doesn't seem to be working (no log streams created, no logs).

Is there something different about how custom buses work that affects log delivery? Is the custom bus the reason you're using an AWS::Logs::ResourcePolicy here instead of this Role-based permission ☝️ ?
