How to use the @dagonmetric/ng-log.LogLevel.Critical function in @dagonmetric/ng-log

log(logLevel: LogLevel, message: string | Error, logInfo?: LogInfo): void {

            properties.description = typeof message === 'string' ? message : `${message}`;
            properties.fatal = logLevel === LogLevel.Critical;

            this._analytics$.pipe(
                tap((analyticsService) => {
                    analyticsService.logEvent('exception', properties);
                }),
