How to config the webpack properly to include the contentscript js file via executeScript?

For some reasons, i want to executeScript from the background.js
```
chrome.scripting.executeScript(
{
target: { tabId: aTab.id },
files: [
// get selection, send it to background (here), wait for response, replace selection
"/my_content_script.js"
]
});
```

However, in such a case, the `my_content_script.js` is not recognised by the webpack. I have to put it in `public` instead of `src`.

Any suggestion ? or just put into public ?
