Setup:
Brave: Version 1.73.104 Chromium: 131.0.6778.204 (Official Build) (64-bit)
Mailvelope: 6.0.1 using GnuPG
Without gmail API

When I try to sign-only an email and select a key (none was pre-selected) nothing happens. Mailvelope remains open, email text in gmail stays empty

On the other hand, when I write an encrypted email, the ciphertext is pasted into gmail
