"It a desktop application. So I'm not porting it from web app nor I plan to make it a web app any time in the future."

Don't use electron.

Unless you are making an app that will majorly benefit from JS-based third party plugins (think how VS code is electron despite not being a progressive web app), there's really no benefit for you to shipping an electron-based app.

Seriously take a look at [maui](https://mauikit.org), I'm considering it for my next GUI projects.
