It seems that latest electron versions use the entitlements to check if audio must be enabled or not.

We need to add this new one in the parent.plist file

com.apple.security.device.audio-input

Apart from that, we have to add the following node packages:

"electron-builder-lib": "^20.23.1",

and update the version of

"electron-builder-squirrel-windows": "^20.23.0",

And, also, in package.json we have to force AppImage:

linux: ... "target": "AppImage",
