   2. In the Redirect URLs section, add the OAuth endpoint that Amazon Lex provided in the preceding step. Choose Add, and then choose Save URLs.

   3. In the Bot Token Scopes section, add two permissions with the Add an OAuth Scope button. Filter the list with the following text:

      • chat:write

      • team:read

3. Update the Interactivity & Shortcuts feature by updating the Request URL value to the endpoint that Amazon Lex provided in the preceding step. Enter the endpoint that you saved in step 3, and then choose Save Changes.

4. Subscribe to the Event Subscriptions feature as follows:

   • Enable events by choosing the On option.

   • Set the Request URL value to the endpoint that Amazon Lex provided in the preceding step.

   • In the Subscribe to Bot Events section, select Add Bot User Event and add the message.im bot event to enable direct messaging between the end user and the Slack bot.

   • Save the changes.

5. Enable sending messages from the messages tab as follows:

   • From the left menu, choose App Home.

   • In the Show Tabs section, choose Allow users to send Slash commands and messages from the messages tab.
