Split-gpg wit debian-11-minimal

I try to use split-gpg with a debian-11-minimal template.

I followed the instructions from Split GPG | Qubes OS and with the debian-11 template every thing works fine.
But with the minimal-template i can’t unlock my private key from mail- qube.
When i unlock the private key in gpg-qube it works and i can use the mail qube as intended.
Guess the gpg-agent has to be set up the right way…

systemctl --user status gpg-agent:
