  okButton: { 
    text: 'Delete',
    click: () => { /* delete logic */ dialogObj.hide(); }
  },
  cancelButton: { 
    text: 'Cancel',
    click: () => dialogObj.hide() 
  }
});

  okButton: {
    text: 'Submit',
    click: () => {
      const name: string = (document.getElementById('nameInput') as HTMLInputElement).value;
      console.log('Name:', name);
      dialogObj.hide();
    }
  }
