d3 version 6 zoom functionality not working."export 'event' was not found in 'd3-selection'

Question

I had installed d3Charts using npm install d3 && npm install @types/d3 --save-dev.

d3 version info in package.json

"dependencies": {
   "d3": "^6.1.1",
}
"devDependencies": {
    .....
    "@types/d3": "^5.7.2",
      ....
}

Below is the code snippet. Chart is coming up properly only getting issues with zoom functionality.

Error:"export 'event' was not found in 'd3-selection'

import { DOCUMENT } from '@angular/common';
import { Component, Inject, OnInit } from '@angular/core';
import * as d3 from 'd3';

      let transform = d3.zoomIdentity.translate(200, 0).scale(1);
      let zoom = d3.zoom().scaleExtent([0.5,10]).on("zoom", handleZoom);

  function handleZoom() {
          if ( svg ) {
              svg.attr("transform", d3.event.transform);
          }

Under @types, checked the index.d.ts
