Sharepoint spfx、onListViewUpdated()异步

Question

我需要在ListView命令集扩展中实现一个按钮，该按钮只有在用户对列表中的选定项具有编辑权限时才可见。因此，我必须在onListViewUpdated()方法中进行异步api调用，但我似乎无法工作，因为onListViewUpdated()不能用作aync函数。有谁有解决这个问题的办法吗？

检查此thread。

@override
public onListViewUpdated(event: IListViewCommandSetListViewUpdatedParameters): void {
  // Get commands
  const commandOne: Command = this.tryGetCommand('COMMAND_1');
  const commandTwo: Command = this.tryGetCommand('COMMAND_2');

  // Command checks
  if (commandOne) {
    this._hideCommandByPermissionSet(commandOne, SPPermission.editListItems);
  }
  if (commandTwo) {
    this._hideCommandByPermissionSet(commandTwo, SPPermission.approveItems);
  }
}

private _hideCommandByPermissionSet(crntCommand: Command, permission: SPPermission) {
  if (this.context.pageContext.list.permissions.hasPermission(permission)) {
    crntCommand.visible = true;
  } else {
    crntCommand.visible = false;
  }
}
