按鈕可讓使用者回答問題或選取所需的按鈕，而不必使用鍵盤輸入回應，來增強交談體驗。 不同於在豐富卡片內出現的按鈕（即使在選取之後仍可供使用者看見且可供存取），在使用者進行選取之後，出現在建議動作窗格中的按鈕將會消失。 這可防止使用者在交談中選取過時的按鈕，並簡化 Bot 開發，因為您不需要考慮該案例。
注意
Bot Framework JavaScript、C# 和 Python SDK 將會繼續受到支援，不過，Java SDK 即將淘汰，最終長期支援將於 2023 年 11 月結束。
使用 Java SDK 建置的現有 Bot 將繼續運作。
針對新的 Bot 建置，請考慮使用 Power Virtual Agents ，並閱讀 選擇正確的聊天機器人解決方案。
如需詳細資訊，請參閱 Bot 建置的未來。
