/**
 * Interactions which allow message replies in the channel they were used in.
 *
 * <p>These replies automatically acknowledge the interaction and support deferring.
 *
 * <p><b>Deferred Replies</b><br>
 *
 * If an interaction reply is deferred using {@link #deferReply()} or {@link #deferReply(boolean)},
 * the {@link #getHook() interaction hook} can be used to send a delayed/deferred reply with {@link InteractionHook#sendMessage(String)}.
 * When using {@link #deferReply()} the first message sent to the {@link InteractionHook} will be identical to using {@link InteractionHook#editOriginal(String)}.
 * You must decide whether your reply will be ephemeral or not before calling {@link #deferReply()}. So design your code flow with that in mind!
 *
 * <p>If a reply is {@link #deferReply() deferred}, it becomes the <b>original</b> message of the interaction hook.
 * This means all the methods with {@code original} in the name, such as {@link InteractionHook#editOriginal(String)},
 * will affect that original reply.

     * <p><b>You only have 3 seconds to acknowledge an interaction!</b>
     * <br>When the acknowledgement is sent after the interaction expired, you will receive {@link net.dv8tion.jda.api.requests.ErrorResponse#UNKNOWN_INTERACTION ErrorResponse.UNKNOWN_INTERACTION}.
     * <p>If your handling can take longer than 3 seconds, due to various rate limits or other conditions, you should use {@link #deferReply()} instead.
     *
     * <p><b>Resource Handling Note:</b> Once the request is handed off to the requester, for example when you call {@link RestAction#queue()},
     * the requester will automatically clean up all opened files by itself. You are only responsible to close them yourself if it is never handed off properly.
     * For instance, if an exception occurs after using {@link FileUpload#fromData(File)}, before calling {@link RestAction#queue()}.
     * You can safely use a try-with-resources to handle this, since {@link FileUpload#close()} becomes ineffective once the request is handed off.
