A workaround to reveal specific logging is to give it a %{public}@ tag os_log("UNNotificationServiceExtension thumbnail_url urlString: %{public}@", log: OSLog.debugGeneral, String(describing: urlString))

This stopped working at least as of macOS 13.6.2 (22G320). Any suggestions as to how to enable private logging now? I need it to debug an iOS Service Notification Extension.
