PGP key does not get detected for SSH authentication with a GNUPGHOME

I've been trying to use my PGP key for SSH authentication following the relevant wiki entry. I'm able to make it work but run into trouble when I try to migrate it to a custom $GNUPGHOME.

$ gpg --list-keys
/home/frontear/.gnupg/pubring.kbx
---------------------------------
pub   rsa3072 2023-08-28 [SCEA]
      A1781A61AD12A4D2F22C14C036E3DA970EE64512
uid           [ultimate] Ali Rizvi <alirizv922@icloud.com>
uid           [ultimate] Ali Rizvi (for github) <perm-iterate-0b@icloud.com>

$ ssh-add -L
ssh-rsa [removed for privacy]

I seem to run into trouble the moment I try to change my gnupg directory to a different place with the GNUPGHOME environment variable. I follow the recommendation in the gpg-agent blurb in the wiki which states to update the systemctl services with the new, non-default directory, and I do this, but while my keys will show, ssh-add -L displays no keys available, even though I still have a configured $GNUPGHOME/sshcontrol file and the systemctl sockets are all correctly configured as well. I don't understand what's going wrong between my migration, I migrate the folders, add the environment variable, migrate the systemctl services, but yet the keys will not be read for ssh authentication. I'm struggling to figure this out because I feel like I've followed every step of the wiki perfectly, to no avail. It will work completely fine without a custom gpg directory, just when I try to setup my custom one to move things out of my home directory.
