Signing a message with S/MIME in Gnus? |

Hello,
anyone here familiar with Gnus + S/MIME + gnupg?
A few days back I decided to set up my environment to sign messages I
send out, and to be able to verify signatures of messages I receive.
Doing it with pgp was quite easy, and got it working in no time, but
S/MIME is giving me a real headache, most probably because I'm
misunderstanding something or because I lack some basic knowledge on how
certificates are meant to be used.
I imported my certificate with 'gpgsm --import <cert.p12>' and "gpgsm
-K" shows that the certificate got imported correctly:
,----
| $ gpgsm -K
| /home/angelv/.gnupg/pubring.kbx

| Subject: /CN=DE VICENTE GARRIDO ANGEL MANUEL - ....

My ~/.gnupg/gpgsm.con just contains:
,----
| disable-crl-checks
`----
and with that, I can sign a file in the command line without problems:
,----
| $ gpgsm --sign test.txt >ciphertext
| gpgsm: Note: non-critical certificate policy not allowed
| gpgsm: Note: non-critical certificate policy not allowed
| gpgsm: Note: non-critical certificate policy not allowed
| gpgsm: CRLs not checked due to --disable-crl-checks option
| gpgsm: DBG: adding certificates at level -2
| gpgsm: signature created
`----
But when I try to sign a message from Gnus I always get a message saying
"No sign key for <angel.de.vicente@iac.es>; skip it? (y or n)"
What do I have to configure in Emacs/Gnus so that it will know that my
e-mail address is linked to the same certificate used in the command
line?
By the way, I'm using the following:
,----
| ArchLinux
| Emacs version: 28.2 (2022-09-12)
| Gnus version: 5.13
| GnuPG version: 2.2.40
`----
Any pointers/help greatly appreciated
