Why not use FreeTube (https://github.com/FreeTubeApp/FreeTube) then if it is based on Electron anyway? Freetube also has support for watching videos directly alongwith downloading and can also route the video through Invidious servers if you prefer not giving your IP address to Youtube.
It's a wholly different use case. FreeTube is meant as a full replacement for the YouTube site. This app is a frontend for youtube-dl and concentrates on quick downloads noly.
