No types definition found for Tables

Target Application

Microsoft Teams

Application Operating System

iOS

Schema Version

1.5

Problem Description

When I check the type for IAdaptiveCard['body'] I see this:

export interface IAdaptiveCard extends ICardElement {
   // ...other properties
    body?: (ITextBlock | IImage | IImageSet | IFactSet | IColumnSet | IContainer)[];
}

I was trying to use Table for which there is no type definition. Same stand for msteams. Please suggest solution if I am missing something.

Expected Outcome

I should not have to define types for Table and msteams.
At the moment I have this to solve my issue:

import type { IAdaptiveCard } from 'adaptivecards';
import type {
  IOpenUrlAction,
  IShowCardAction,
  ISubmitAction,
  Spacing,
  TextColor,
} from 'adaptivecards/lib/schema';

type TableColumn = {
  width?: number;
};

type TableCell = {
  type: 'TableCell';
  style?: TextColor;
  items: IAdaptiveCard['body'];
};

export type TableRow = {
  type: 'TableRow';
  style?: TextColor;
  cells: TableCell[];
};

type Table = {
  type: 'Table';
  spacing?: Spacing;
  gridStyle?: 'default' | 'accent';
  firstRowAsHeader?: boolean;
  showGridLines?: boolean;
  firstRowAsHeaders?: boolean;
  columns?: TableColumn[];
  rows?: TableRow[];
};

type MsTeams = {
  entities: {
    type: 'mention';
    text: string;
    mentioned: {
      id: string;
      name: string;
    };
  }[];
};

type Body = NonNullable<IAdaptiveCard['body']>[number] | Table;
type IAdaptiveCardWithoutBody = StripIndexSignature<
  Omit<IAdaptiveCard, 'body' | 'actions'>
>;

type ShowCardActionWithOutCard = Omit<IShowCardAction, 'card'>;
type ShowCardActionWithCard = ShowCardActionWithOutCard & {
  card: AdaptiveCard;
};

export type AdaptiveCard = Partial<IAdaptiveCardWithoutBody> & {
  body?: Body[];
  actions?: (ISubmitAction | IOpenUrlAction | ShowCardActionWithCard)[];
};

export type MsTeamsContent = AdaptiveCard & { msteams: MsTeams };

Actual Outcome

I get this error without above changes:

Card JSON

Cannot share private data but I think it is irrelevant.

Repro Steps

No response

Start by locating the TypeScript definition of IAdaptiveCard and the existing schema declarations for body elements. Compare the missing Table and msteams definitions with the Adaptive Card schema version 1.5 and the platform extension described in the issue. Done means consumers can use those card shapes without local type overrides, with the relevant type checks passing.
