The compose trigger event object (e.gmail) in Gmail add-ons lacks properties to read or edit the draft body, even after autosave, restricting functionality to subject-only operations.

Steps to Reproduce:

Create a compose trigger add-on:

"gmail": {"composeTrigger": {"selectActions": [{"text": "Test", "runFunction": "test"}],"draftAccess": "METADATA"}} Try to read/edit the draft:

  var draftId = e.gmail.draftId; // Undefined
  var text = draftId ? GmailApp.getDraft(draftId).getMessage().getPlainText() : "No draftId";
  // Attempt to edit: GmailApp.getDraft(draftId).update(...);
  return CardService.newCardBuilder().setHeader(CardService.newCardHeader().setTitle("Test")).addSection(CardService.newCardSection().addWidget(CardService.newTextParagraph().setText(text))).build();
}

Deploy, compose an email, wait for autosave, and click the button.

Actual Result:

e.gmail only provides {"subject":"[typed subject]"}; draftId and accessToken are undefined. Can’t read the body (e.g., via GmailApp.getDraft()) or edit it (e.g., via update()), resulting in errors like "Not found" or "Missing access token."

Expected Result:

e.gmail should include draftId and accessToken to enable reading the body (e.g., GmailApp.getDraft(draftId).getMessage().getPlainText()) and editing it (e.g., GmailApp.getDraft(draftId).update(...)).

Impact:

Blocks compose-time add-ons needing to process or modify the draft body (e.g., spell checkers, formatters).
