New features and capabilities

Partial Support for Teams JS SDK in Adaptive Card Extensions (Mobile only)

Developers can access partial Teams JS SDK in Adaptive Card Extensions via ACE's context (in the same way as in web parts). This enables the Adaptive Card Extensions to reflect the user interface based on the Microsoft Teams mobile theme setting.

class AdaptiveCardExtensionContext {
  // ...
  public sdks: IPartialSDKs | undefined;

// Accessing the theme details using context


Currently availability of this SDK is limited to Viva Connections Mobile only. We are working on introducing the support for this feature for the desktop and web clients in future releases.


Currently we only provide access to the theme property of the appInfo object of the Teams' context for Adaptive Card Extensions.
