- handler
- CardButtonClickedHandler<TState>
Function to call when the event is triggered.

Remarks
The `composeExtension/onCardButtonClicked` INVOKE activity does not contain any sort of command ID, so only a single select item handler can be registered. Developers will need to include a type name of some sort in the preview item they return if they need to support multiple select item handlers.
