How to use the @fullstack-one/helper.AHelper.requireFilesByGlobPattern function in @fullstack-one/helper

private async loadPermissions(): Promise {
    const permissionsPattern = this.ENVIRONMENT.path + this.schemaBuilderConfig.permissionsPattern;
    const permissionsArray: IPermission[] = await AHelper.requireFilesByGlobPattern(permissionsPattern);
    this.logger.trace("boot", "Permissions loaded");
    const decoratorPermissions = getDecoratorPermissions();
    return [].concat.apply([], permissionsArray).concat(decoratorPermissions);
  }
