/**
 * {@link PaginationAction PaginationAction} that paginates the thread members endpoint.
 * 
Note that this implementation is not considered thread-safe as modifications to the cache are not done
 * with a lock. Calling methods on this class from multiple threads is not recommended.
 *
 * Must provide not-null {@link IThreadContainer IThreadContainer} to compile a valid
 * pagination route.
 *
 * 
Limits:

 * Minimum - 1
 * 
Maximum - 100
 *
 * 
Example

 * 
{@code
 * // Clean up all private threads older than 2 weeks
 * public static void cleanupPrivateThreads(TextChannel channel) {
 *     // get 2-week offset
 *     long 2WeekAgoTimestamp = System.currentTimeMillis() - (14 * 24 * 60 * 60 * 1000);
 *     // get paginator
 *     ThreadChannelPaginationAction threads = channel.retrieveArchivedPrivateThreadChannels();
 *     // remove each thread older than 2 weeks
 *     threads.forEachAsync((thread) ->
 *         long threadArchiveTimestamp = thread.getTimeArchiveInfoLastModified().toInstant().toEpochMilli();
 *         if (threadArchiveTimestamp < 2WeeksAgoTimestamp) {
 *            thread.delete().reason("Cleaning up old private threads").queue();
 *         }
 *     );
 * }
 * }
