Basic import does not work

[TLescoatTFX]

Here is a part of rollup.config.js:

import inlineCode from 'rollup-plugin-inline-code'
console.log(inlineCode);
console.log(inlineCode());

Actual result:

> npx rollup -c rollup.config.js --bundleConfigAsCjs

{ default: [Function (anonymous)] }
[!] TypeError: inlineCode is not a function

Expected result:

> npx rollup -c rollup.config.js --bundleConfigAsCjs

[Function (anonymous)]
{
  name: 'rollup-plugin-inline-code',
  resolveId: [Function: resolveId],
  transform: [Function: transform]
}

I can get the expected output using inlineCode.default, but that is clearly not the way it is supposed to work.
