How to use html-webpack-plugin variable inside <script>?

I am trying to assign variable inside <script> tag by means of html-webpack-plugin where the variable is located. I can easily use it inside html tags like title <%= htmlWebpackPlugin.options.applicationId %>

My html-webpack-plugin looks like :

new HtmlWebpackPlugin({
      filename: config.build.index,
      template: 'index.html',
      inject: true,
      applicationId : process.env.APPLICATION_ID ?process.env.APPLICATION_ID : 1,
      minify: {
        removeComments: true,
        collapseWhitespace: true,
        removeAttributeQuotes: false
        // more options:
        // https://github.com/kangax/html-minifier#options-quick-reference
      },
      // necessary to consistently work with multiple chunks via CommonsChunkPlugin
      chunksSortMode: 'dependency'
    }),

And I want to use variable applicationId on index.html page with following script :

<script type="text/javascript">
      var xhr = new XMLHttpRequest();
      xhr.onreadystatechange = function() {
        if (xhr.readyState == XMLHttpRequest.DONE) {
          document.write(xhr.responseText);
        }
      };
     var appId = <%= htmlWebpackPlugin.options.applicationId %>;
   xhr.open("GET","https://somesite.com/NavigationApi/api/content/get?applicationId=" + appId,false);
      xhr.send(null);
    </script>
