+      # ### `:notification_payload_transform`
+      #
+      # - `proc` **default** `nil`
+      #
+      # Specifies custom proc used to extract span attributes form the notification payload.

+      # - `boolean`  **default** `false`
+      #
+      # Specifies whether spans names should use the legacy format where the subscription was reverse ordered and white space separated. (Ex. `action_view render_template`)
+      # If set to `true`, the span name will match the name of the notification itself. (Ex. `render_template.action_view`)
