SharePoint extension command set

问题

SharePoint Modern: Is it possible to add an custom action using command set for a particular list or how to activate a custom action for specific list? I am trying to develop a custom action for specific list but when I deployed in SharePoint tenant this custom action is added for all list(same type of list template).

Here is my test solution to limit command set extension to specific list.

We could get current list title by this.context.pageContext.list.title.

@override
  public onListViewUpdated(event: IListViewCommandSetListViewUpdatedParameters): void {    
    const compareOneCommand: Command = this.tryGetCommand('COMMAND_1');
    if (compareOneCommand) {
      // This command should be hidden unless exactly one row is selected.
      compareOneCommand.visible = this.context.pageContext.list.title === 'MyList3';      
    }
  }

Yes it is.. You can check it with the list id, and if matches make command.visible == true
