Notes

All components follow a rule. The required parameters are all placed in foward arguments. Other optional parameters setting in last argument.
For example:

// In url button, the first two arguments are required.
// Last argument with object is used to setting optional parameters.
new ButtonUrl(
  'View Website', /* required */
  'https://peterssendreceiveapp.ngrok.io/view?item=103', /* required */
  {
    messengerExtensions: true,  /* optional */
    webviewHeightRatio: 'tall', /* optional */
    fallbackUrl: 'https://peterssendreceiveapp.ngrok.io/' /* optional */
  }
);
