`maxStackDepth` | A value in the reentrancy configuration that controls how many reentrant calls be made to the same actor.
`entitiesConfig` | Array of entity configurations that allow per actor type settings. Any configuration defined here must have an entity that maps back into the root level entities.

Actor settings in configuration for timeouts and intervals use [time.ParseDuration](https://pkg.go.dev/time#ParseDuration) format. You can use string formats to represent durations. For example:
- `1h30m` or `1.5h`: A duration of 1 hour and 30 minutes
- `1d12h`: A duration of 1 day and 12 hours
- `500ms`: A duration of 500 milliseconds
