A UI object can only have one of setOpenLink(openLink), setOnClickAction(action), setOnClickOpenLinkAction(action), setAuthorizationAction(action), or setComposeAction(action, composedEmailType) set.

// ...

const action = CardService.newAuthorizationAction().setAuthorizationUrl('url');
CardService.newTextButton().setText('Authorize').setAuthorizationAction(action);

Parameters

Name	Type	Description
`action`	`AuthorizationAction`	The object that specifies the authorization action to take when this element is clicked.

`setBackgroundColor(backgroundColor)`

The Action parameter must specify a callback function that returns a ComposeActionResponse object configured using ComposeActionResponseBuilder.setGmailDraft(draft).

Note: This method doesn't set a compose action that is used to extend the compose UI. Rather, this method connects this UI element to an Action that composes draft messages in Apps Script that are opened in Gmail when the action completes.

const action = CardService.newAction().setFunctionName('composeEmailCallback');
CardService.newTextButton()
    .setText('Compose Email')
    .setComposeAction(action, CardService.ComposedEmailType.REPLY_AS_DRAFT);

function composeEmailCallback(e) {
  const thread = GmailApp.getThreadById(e.threadId);
  const draft = thread.createDraftReply('This is a reply');
