Elementor Pro password re-directs to priavte website area

I offer advertising space on my site through banner ads. I have an advertising landing page where potential advertisors can learn more about how they can advertise on my site and what it entails, etc. I am using Elelmentor Pro to make my advertising landing page. I have an idea that in addition to my basic advertising landing page I would like to target specific advertisors and provide them with a special code or password that they can enter through a form submission on my advertise landing page, and then depending on the code or password they enter, they would then be re-directed to a private area on my site that only they can see, and their “test ads” would be displayed. The ides being that this is what it would look like if their ads were actually running on my site. So my two main questions are as such:

1. How would I go about setting this up?
2. Do I need any extra plugins to make this work?

I am using Elelemntor Pro to build the landing page, and i also have the Restrict Content Pro plugin enabled as well.

In Elementor Pro, is it possible to enter just a code or password into a form, and then be re-directed to a private are of my site based upon that code or password?

Just to be clear, I AM NOT looking for a “login form.” I already know how to create one in Elementor. I want just a form so potential advertisors c an simply enter a code or password and then be redirected to a private area based upon that code or password.

Is this possibe?
