How can i use the plugin with webpack-chain

[fxylee]

First: I have no problem using it through webpack.config.js.
But I can't get compiled results when i use chainWebpack to config webpack,
So I'm not sure my configuration code is correct.

config.module
  .rule('graphql')
     .test(/\.graphql$/)
  .include
    .add(path.resolve(__dirname, 'src'))
    .end()
  .exclude
    add(/node_modules/)
    .end()
  .use('graphql-tag/loader')
    .loader('graphql-tag/loader')
    .end();

# demo.graphql
query Demo {
  uv
}

I got a Base64 string when I imported it

import DemoGQL from './demo.graphql'
