So, Electron builds on Linux (within certain constraints), and all you have to do is change the user agent presented in order to get it to work for voice (something that Electron allows you to do).
Sounds like someone is deliberately holding this back rather than being technically stymied.
This is still being worked upon. I hope to have more details in the next couple months.
Please know the team is actively working on this feature.
