Problems configuring Howdy by adding a change to a PAM file

The problem is self explanatory, I have installed the dependencies and followed the official Howdy guide for Arch linux, but I can’t get Howdy to activate in the unlock menu, if I put a blank password it doesn’t even try to activate the camera.

I have previously managed to get Howdy working in Manjaro Gnome, but when I changed distro due to problems using AUR apps, what I have described happens to me, now I use EndeavourOS Plasma if that helps.

I should mention that the guide says to add “to any configuration file in /etc/pam.d/” but when I did it in Manjaro it only worked for me in the “system-login” PAM file.

This is my hardware info in case that helps: https://0x0.st/o7eg.txt

Thanks you all for bothering to read me!
