Which commit implemented the change @Lenakh97?

[coderbyheart]

Still used Lambda.Function: https://github.com/hello-nrfcloud/public-parameter-registry-aws-js/blob/saga/cdk%2FRegistryStack.ts#L94

Should use https://github.com/bifravst/aws-cdk-lambda-helpers/blob/saga/src%2FPackedLambdaFn.ts
