 *
 * On the liveapp side, we ensure that pending messages are held until the block registers the
 * callback (or another message is sent). If there's a pending message, it is returned at
 * registration.
 *
 * This class implements AbstractModelWithAsyncData in order to take advantage of useLoadable's
 * suspense handling. "Loading" the model means registering the handler with liveapp. This allows us
 * to suspend the block and return the initial pending message on first render.
 *
 * One difference is that _unloadData will not unregister the airtableInterface handler. We don't
 * support unregistering it at this time for simplicity.
 *
 * This class is internal: users should use registerRecordActionDataCallback or useRecordActionData.

/**
 * Registers a callback to handle "open block" / "perform record action" events (from button field).
 *
 * Returns a unsubscribe function that should be used to unregister the callback for cleanup on
 * component unmount, or if you wish to register a different function.
 *
 * Also see {@link useRecordActionData}, which subscribes to the same events in a synchronous way.
 *
 * Your block will not receive "perform record action" events until a callback is registered -
 * they're held until registration to ensure the block is ready to handle the event (e.g. has
 * finished loading).
 *
 * Because of this, we recommend only registering a callback once, in your top level component -
 * otherwise, messages could be received while not all callbacks have been successfully registered.
 * Similarly, using both `registerRecordActionDataCallback` and `useRecordActionData` is not
 * supported.
 *
 * You can test your block in development by sending "perform record action" events to your block
 * in the "Advanced" panel of the block developer tools.
 *
 * After releasing your block, you can use it with a button field by choosing the "Open custom
 * block" action and selecting your block.
 *
 * @example
 * ```js
 * import React, {useEffect, useState} from 'react';
 * import {registerRecordActionDataCallback} from '@airtable/blocks/ui';
 *
 * function LatestRecordAction() {
 *     const [recordActionData, setRecordActionData] = useState(null);
 *
 *     const callback = (data) => {
 *         console.log('Record action received', data);
 *         setRecordActionData(data);
 *     }
 *
 *     useEffect(() => {
 *         // Return the unsubscribe function so it's run on cleanup.
 *         return registerRecordActionDataCallback(callback);
 *     }, [callback]);
 *
 *     if (recordActionData === null) {
 *         return <span>No events yet</span>;
 *     }
 *
 *     return (
 *         <ul>
 *             <li>Record id: {recordActionData.recordId}</li>
 *             <li>View id: {recordActionData.viewId}</li>
 *             <li>Table id: {recordActionData.tableId}</li>
 *         </ul>
 *     );
 * }
