### Listen config
If `type` is `unix`, `path` is the path where to create the socket.

If `type` is `tcp`, `port` and `host` are the host/port where to listen.

### Profile directory
The `profile_dir` specifies which directory to put Chromium user data directories.

### URL
`url` specifies the URL of the index page of the LINE extension for your Chromium installation.

### Extension directory
The `extension_dir` specifies which directory contains the files for the LINE extension, which you must download yourself.

### Cycle delay
`cycle_delay` specifies the period (in milliseconds) at which Puppeteer should view chats to check on their read receipts. Only chats with messages that haven't been fully read need to be checked.

### `xdotool`
Set `use_xdotool` to `true` to allow the Node process to manipulate the mouse cursor of the X server it runs in. Requires the `xdotool` utility to be installed. Highly recommended, especially when running in a background X server. Its default value is `false` so that running in a non-background X server won't interfere with a real mouse cursor.

`jiggle_delay` specifies the period (in milliseconds) for "jiggling" the mouse cursor (necessary to keep the LINE extension active). Only relevant when `use_xdotool` is `true`.

### DevTools
Set `devtools` to `true` to launch Chromium with DevTools enabled by default.
