@frankjunior, an unsuccessful attempt has been detailed:

The most useful information that I have located has been:

luminoso/Signal-Desktop

Should be possible now. See https://github.com/signalapp/Signal-Desktop/issues/4530 and here: https://copr.fedorainfracloud.org/coprs/useidel/signal-desktop/build/5735860/
