Chat SDK now supports callback URLs on buttons and modals

You can now pause a Workflow run on a Chat SDK card and resume it when someone clicks a button. The same flow works for form submissions. Buttons and modals accept a new callbackUrl prop, and the event payload is sent to that endpoint.

To build a card like this, create a workflow webhook and pass its URL to each button's callbackUrl prop inside your <Card> component:

For the <Modal> component, the form data is in the payload. callbackUrl works for buttons on most platforms with an official adapter, and for modals on Slack and Teams.
