Specify indentation when infusing

How do I use 4 space indentation instead of 2 space when infusing ?
I tried to add `--prettier=./.prettierrc` when infusing, but it doesn't seem to work.

```js
// .prettierrc
{
    "printWidth": 120,
    "tabWidth": 4,
    "semi": true,
    "singleQuote": true,
    "trailingComma": "all"
}
```
