我为“默认欢迎意图”创建了两个答案。

默认情况下，一个作为文本响应显示在Slack中，另一个作为文本响应显示在Slack中，另一个使用Slack作为我的机器人的通道，单击“添加响应”以开始使用Dialogflows UI为Slack创建响应。

第二个是以下内容，这是从docs轮询的默认模板：

打个招呼时，它应该提供如下图所示的图像：

但是，如果在Integrations中启动测试后出现第一条消息，则即使在右侧的小对话框中也不会显示第二条消息。

I thought the problem would be that I needed to make the bot public as it seems that to use rich messages, we have to copy the ‘Events Request URL' value given by Dialogflow and paste it into the 'Request URL' field from the Interactive Messages section of my Slack app settings. But the bot don't even retrieve the default message.

Steps I followed to implement my bot

• In the Slack app, go to the 'Bot users' section and click the 'Add a Bot User' button.
• In the Slack app ‘Basic Information’ section, copy the 'Client ID', 'Client Secret' and 'Verification Token' and paste their values into the respective fields below.
• Start the bot.
• Copy the 'OAuth URL' value below and paste it into the 'Redirect URL(s)' field from the ‘OAuth & Permissions’ section of your Slack app settings. Save URLs.
• Copy Events Request URL from the field below and paste it to Request URL in the ‘Events Subscription’ section of your Slack app.
• Enable events in the ‘Event Subscriptions’ section.
• Select necessary events in "Subscribe to Bot Events" section for example message.im, message.group, message.channel, im_created. These events will define which message types (direct, in channel, etc.) your bot will react to. Save changes. I selected message.im, message.groups, message.channels, im_created
• In the Slack app settings, go to 'Manage Distribution' and add the bot to your Slack team using the 'Add to Slack' button (it bugged there)
