How to get the Gitlab Certification

I have difficulties to understand how’s the gitlab certification concept/path works.
Is the docs information GitLab Technical Certifications- Self-Paced Options | GitLab still relevant right now?

If I am new, what should I take for the first time? and where I can buy the certification? is it already in the bundle? Because in the bundle doesn’t state It has certification inside there.

and can I just straight away to security specialist? GitLab

or Devops professional GitLab

Because in the bundle, it doesn’t said I need to have associate first etc.

Hope I can get more clarification from here…
