Support for setting PreTokenGeneration to v2_0 for access token

[Zhuohui-Li]

Is this feature request related to a new or existing Amplify category?

auth

Is this related to another service?

cognito

Describe the feature you'd like to request

Currently, the amplify cli doesn't support configuring the PreTokenGeneration trigger to v2_0 directly through its configuration

Describe the solution you'd like

amplify update auth
Do you want to enable any of the following capabilities?
Add a Override Access Token option

Describe alternatives you've considered

use amplify override auth
and in override.ts

import {
  AmplifyAuthCognitoStackTemplate,
  AmplifyProjectInfo,
} from "@aws-amplify/cli-extensibility-helper";

export function override(
  resources: AmplifyAuthCognitoStackTemplate,
  amplifyProjectInfo: AmplifyProjectInfo
) {
  resources.userPool.userPoolAddOns = {
    AdvancedSecurityMode: "ENFORCED",
  }; // This works if I just ignore the type error
  resources.userPool.lambdaConfig = {
    preTokenGenerationConfig: {
      // ...
      // This is not currently supported
      // https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cognito-userpool-lambdaconfig.html#cfn-cognito-userpool-lambdaconfig-pretokengenerationconfig
      LambdaVersion: "V2_0",
    },
  };
}

Hey @Zhuohui-Li, thank you for filing this, marking this as feature request.

Note: tried overriding the property but was unable to modify the the property to v2

resources.userPool.addPropertyOverride("LambdaConfig", {
    ...resources.userPool.lambdaConfig,
    PreTokenGenerationConfig: {
      LambdaVersion: "V2_0",
      LambdaArn:
        "<arn>",
    },
  });
