What configuration should be used to obfuscate Angular 18 project with javascript-obfuscator ?

I am using package.json

{
  "name": "angular.dev",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "NG_BUILD_PARALLEL_TS=0 ng serve",
    "build": "ng build --configuration production",
    "watch": "ng build --watch --configuration development"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^18.0.0",
    "@angular/cdk": "^18.0.0",
    "@angular/common": "^18.0.0",
    "@angular/compiler": "^18.0.0",
    "@angular/core": "^18.0.0",
    "@angular/forms": "^18.0.0",
    "@angular/material": "^18.0.0",
    "@angular/platform-browser": "^18.0.0",
    "@aws-amplify/ui-angular": "^5.0.19",
    "aws-amplify": "^6.5.3",
    "rxjs": "~7.8.0",
    "tslib": "^2.3.0",
    "zone.js": "~0.14.0"
  },
  "devDependencies": {
    "@angular-builders/custom-webpack": "^18.0.0",
    "@angular/build": "^18.0.1",
    "@angular/cli": "^18.0.0",
    "@angular/compiler-cli": "^18.0.0",
    "javascript-obfuscator": "^4.1.1",
    "typescript": "~5.5.0",
    "webpack-cli": "^5.1.4"
  }
}

with Angular 18, javascript-obfuscator version 4.1.1 and @angular-builders/custom-webpack version 18.0.0

My angular.json file is

        "serve": {
          "builder": "@angular/build:dev-server",
          "configurations": {

        }
      }
    }
  },
  "cli": {
    "analytics": false
  }
}

and webpack.config.js is

const JavaScriptObfuscator = require('javascript-obfuscator');

module.exports = {
    mode: 'development',
    plugins: [
  new JavaScriptObfuscator(
      {
       rotateStringArray: true,
       stringArray: true,
       stringArrayEncoding: ['rc4'],
       stringArrayThreshold: 0.75,
      },
      ['vendor.js']
  ),
 ],
};

when I am running this project with npm run build i am getting the error :

[error] ValidationError: Invalid configuration object. Webpack has been initialized using a configuration object that does not match the API schema.
 - configuration.plugins[12] misses the property 'apply'. Should be:
   function
   -> The run point of the plugin, required method.

Can anyone suggest which package.json, angular.json and webpack.config.js configuration should be used to obfuscate Angular 18 project using javascript-obfuscator?
Are there any other options to obfuscate Angular 18 project code?
