gpg-agent (macOS) doesn't provide any key for SSH

There are several topics addressing similar issues, but none of the solutions provided there work for my environment, being: - macOS 11.2.3 (MacBookPro M1/Apple silicon) - GnuPG 2.2.27 (installed via Homebrew) - Zsh shell - GPG key with Auth-only subkey for SSH The *~/.gnupg/gpg-agent.conf* file:

pinentry-program /opt/homebrew/bin/pinentry-tty
enable-ssh-support

The *~/.gnupg/sshcontrol* file:

FADD8723...AE7ED (the keygrip retrieved with gpg -K --with-keygrip)

The *~/.zshrc* file:

unset SSH_AGENT_PID
export GPG_TTY="$(tty)"
export SSH_AUTH_SOCK=$(gpgconf --list-dirs agent-ssh-socket)
gpgconf --launch gpg-agent

I made sure *ssh-agent* is not running (also rebooted the system to be sure). But no keys are found when running:

ssh-add -L
The agent has no identities

What am i missing? EDIT: I should add that I also configured a few Debian 10 systems like this and it works just fine.
