bug: neomutt & gpg - ambiguous specification of secret key

[alembiq]

Is there an existing issue for this?

Issue description

my home-manager defines multiple emails for single user, each email has designated pgp key

     home-manager.users.charles.accounts.email.accounts."charles@alembiq.net" = {
....
        gpg = {
          key = "4A72 ....";
          signByDefault = true;
        };
...

when i try to send an email from neomutt, it tries to sign the email, but I'm getting an error message: ambiguous specification of secret key 'charles@alembiq.net'

I didn't found any definition of the key in any of the files in ~/.config/neomutt/
