Automatically unlock gnome-keyring with hyprlock

Hi guys, I’ve been having some troubles with my NixOS configuration. I added gnome-keyring in order to keep my owncloud client unlocked and tried to automatically unlock the keyring upon login (with hyprlock). According to my search online, this should be possible with

services.gnome-keyring.enable = true;
security.pam.services.hyprlock.enableGnomeKeyring = true;

While the keyring works as intended, it is not automatically unlocked upon login. Instead, I need to type my password twice upon boot; once for hyprlock and once for the keyring.

I’ve made sure to set the same password for the keyring as for the hyprlock login. I also tried setting pam_module = hyprlock in the hyprlock configuration, but according to the wiki, this is the default value anyways.

I appreciate any input!
