Comment 3 for bug 1630281

Hello

I tried building the project but the remote part desktop/gtk3 seems to no longer exist. Could you please try updating the package to build again?

Having said that, I had a look at the interface declarations. Can you please look at https://snapcraft.io/docs/desktop-interfaces for an overview of which interfaces to use for desktop applications? I think you want the "desktop" and "x11" interfaces but I cannot try without a way to build the package first.
