+TIP: In other scenarios, you might want to refer to non-required parameters in the Kamelet's `spec.template` using the `{{?optionalParam}}` syntax; that might be helpful for those cases where the non-required parameter does not define a default value in the Kamelet's `spec.definition.properties`. For more information, you can refer to the Camel property placeholder syntax in the https://camel.apache.org/manual/using-propertyplaceholder.html#_using_optional_property_placeholders[Camel manual].
