- * The 'log_reference_generator' should be a numeric array with three elements:
- * - The first element should be the fully qualified name of a class that contains static methods.
- *   This includes the namespace of the class.
- * - The second element should be the name of a static method available in the specified class.
- * - The third element should be an array of optional parameters to pass to the static method.
- * For example, the default generator is configured as follows:
- * [\Illuminate\Support\Str::class, 'random', [12]], which uses the 'random' static method
- * from the \Illuminate\Support\Str class with 12 as a parameter.

+    | - log_reference_prefix: The prefix for the generated reference string.

+    | - log_reference_generator_method: The name of the static method available in the generator class.
