Restricting to resources with valid token using API Gateway and cognitos

[Shreyah]

Able to get Frontend/login authenticated with the Cognito and APIGateway authorizes and redirects if it contains valid token.
I am pretty new to this tech stack so please don't judge me for this question.
 All examples out there creates the API in the API gateway. But, how to use Kubernetes services as the rest api endpoints in the API Gateway?

Appreciate any help here, thanks!
