    Your application should call API Gateway (with cognito), and it trigger your lambda.

    You can create FunctionUrl for your lambda and then make an HTTP Request from your mobile app.

    Steps to create FunctionUrl:

    1. Head to your lambda page on AWS Console
    2. Click on Configuration tab
    3. From the side-panel, choose Function Url
    4. Click "Create Function Url"
    5. Choose the appropriate Auth type, either NONE (anyone can call your function Url) or AWS_IAM (authenticated users or Roles can call the function)
    6. Click Save

    Finally you can copy the function URL and make the request from your mobile app.
