Example:
// MyComponentImpl.tsximport { DynamicContentStore, DynamicComponent } from "@twilio/flex-ui";
export const displayName = "MyComponent";export const contentStore = new DynamicContentStore(displayName);
export class MyComponentImpl extends React.PureComponent { // … render() { return ( <DynamicComponent store={contentStore} // ..add(child, options) => CleanupFunction#
