Is there a way to protect an individual file within a directory using OpenIDC and Redhat SSO?

Question

I'm trying to implement SSO into my localhost website and I'm having issues with which files are being protected. For simplicity, the link takes you to a page with the URL known as localhost/test. I have a button on that page which is supposed to trigger localhost/text/index.cgi. Once the button is pressed, I want the SSO sign in page to pop up.

The issue is, I can't seem to configure it so that it's just index.cgi being protected. No matter what I try, the /test/ directory is the one being protected, as signaled by the fact that it prompts an SSO sign in when clicking the link on the homepage.

Here's what I have so far, based on some brief research I did (Assume that OIDC configuration is working, I don't think I'm allowed to share that):

<LocationMatch "^/test/((?!index.cgi).)*$">
    Require all granted
</LocationMatch>

<Location /test/index.cgi>
    AuthType openid-connect
    Require valid-user
</Location>

These blocks are located inside my virtual host config for Apache. From what I read, the first block is supposed to allow access to all files located within /test/ except for index.cgi. The second block prompts the SSO login for index.cgi.

I've also tried using a standard Location block with /test/ with Require all granted but it still didn't work.
