Offer a verified Flatpak

[PerAstraAdDeum]

Hi there,

if you can, please offer a verified Flatpak for your app. As you may know Flatpak is rapidly growing and evolving, passing four million users and over two billion downloads last year. It offers many security features and would make the installation of Bitbox Wallet even easier.

Best regards

Would be nice if it was supported in fpm, the tool we use to create the .deb and .rpm packages.
