Enabling permission for WebSerial in Desktop version

[ale3andro]

Hello,
I have managed to create an extension that interacts with an Arduino board and I am able to load and use it in the web editor (unsandboxed).
The problem is that the same extension does not work in the electron desktop version. It seems that the electron does have the necessary permission to list serial ports and open a list of serial ports. Is there a way to allow such a permission in a custom electron build?
Thank you.

electron is supposed to support it but we disable a lot of permissions

you'll probably need to make a few changes to files in this repository:

• you have to enable the serial permission - probably handlePermissionCheck in src-main/windows/project-running-window.js
• electron does not have a builtin interface for picking devices, so you have to implement select-serial-port event in main process somewhere. some vague example on https://www.electronjs.org/docs/latest/tutorial/devices#web-serial-api. easiest place to add that would probably be src-main/index.js under app.on('session-created',
