 * Defers the display of given in-app message for a future pageload.
 * The deferred in-app message can be retrieved by calling [[`getDeferredInAppMessage`]],

 *  Deferring an in-app message will overwrite any previously deferred in-app message.
 *
 * Note: Be sure to subscribe to clicked / dismissed events on this in-app message only after retrieving it using [[`getDeferredInAppMessage`]].
 *  Any subscriptions made before calling [[`deferInAppMessage`]] will not be persisted.
 *  Also note that the in-app message deferred here will be cleared out when in-app message triggers have been refreshed from the Braze backend.
 *
 * @param inAppMessage - The message to defer for later display.
 *
 * @returns Resolves to whether or not the message was successfully deferred.
 * Returns undefined if the SDK has not been initialized.
