Customization of Page Restrict Plugin

Hello developers,
I am using a plugin namely “Page Restrict”. The plugin by default displays its own version of a login form and redirects the user to that login form page in case of a page restrict. However, I want to modify the plugin such that when user tries to access restricted page, they are redirected to my URL of my custom Login / Registration Form. I have been trying to modify the code but to no avail. Can someone please help me out and guide me in the right direction? I’ll be really thankful.

Best regards,
Fariha Rehman
