/**
 * Checks whether users can access the provided resources.
 *
 * `useCanAccessResources` returns an object describing the state of the request:
 *
 * - start: { isPending: true }
 * - success: { canAccess: Object<string, boolean>, isPending: false }
 * - error: { error: [error from provider], isPending: false }
 *
 * @param {Object} params Any params you want to pass to the authProvider
 * @param {string} params.action The action to check access for
 * @param {string[]} params.resources The list of resources to check access for
 * @param {Object} params.record Optional. The record to check access for
 *
 * @returns Return the react-query result and a canAccess property which is a map of the resources and their access status { [resource: string]: boolean }
 *
 * @example
 * import { useCanAccessResources } from 'react-admin';
 *
 * const UserList = ({ record }) => {
 *     const { isPending, canAccess } = useCanAccessResources({
 *         action: 'read',
 *         resources: ['users.id', 'users.name', 'users.email'],
 *         record
 *     });
 *
 *     if (isPending) {
 *         return null;
 *     }
 *     return (
 *         <SimpleList
 *              primaryText={record => canAccess.users.name ? record.name : ''}
 *              secondaryText={record => canAccess.users.email ? record.email : ''}
 *              tertiaryText={record => canAccess.users.id ? record.id : ''}
