/**
 * {@link 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 ThreadChannel} to compile a valid
 * pagination route.
 *
 * 
Limits:

 * Minimum - 1
 * 
Maximum - 100
 *
 * 
Example

 * 
{@code
 * // Count all thread members who are bots
 * public static CompletableFuture countBotMembers(ThreadChannel thread) {
 *     AtomicInteger count = new AtomicInteger();
 *     ThreadMemberPaginationAction members = thread.retrieveThreadMembers();
 *     return members.forEachAsync((threadMember) -> {
 *         if (threadMember.getUser().isBot())
 *             count.incrementAndGet();
 *         return true; // continues iterating if this returns true
 *     }).thenApply((v) -> count);
 * }
 * }
