AlexaSkill trigger does not appear in Lambda console

[JoeShi]

I use the following serverless.yml to deploy. It can deploy successfully, but does not show up the AlexaSkill trigger on lambda console. Any help?

 functions:
    toggleFan:
    handler: index.handler
    events:
      - alexaSkill:
          appId: amzn1.ask.skill.5184fa42-6c79-4ee9-a6d4-d6f0dc47fc29
          enabled: true
