I see an article that invoke / handle is asynchronous, but it's possible to use the old send / on. It is easy to return the return value. You do not need to specify webcontents when sending from Main to renderer. The benefits are understandable
https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31 I don't think the remote module written in this article is relevant to send / on

The ipcMain module is used to communicate asynchronously from the main process to renderer processes. When used in the main process, the module handles asynchronous and synchronous messages sent from a renderer process (web page). The messages sent from a renderer will be emitted to this module.
To send a message back to the renderer you would use: win. webContents. send('asynchronous-message', {'SAVED': 'File Saved'});
invoke is new api to help ergonomics around existing send / on pair when try to invoke some fn to return values to the sender. You can achieve same thing via send if you prefer to use it, there's no functional differences.
