Issue with Streams : myDynamoDBFunction = defineFunction

Trying to create a stream for my existing table in dynamodb using awsamplify as per the information given on the url https://docs.amplify.aws/react/build-a-backend/functions/examples/dynamo-db-stream/ when i go to define the function using this code import { defineFunction } from "@aws-amplify/backend";

export const myDynamoDBFunction = defineFunction({
name: "dynamoDB-function",
resourceGroupName: "data",
}); I get error saying resourceGroupName not recognized.
