Action by clicking the submit button

Hello Support.

I need to create an action on the submit button of Contact Form 7. For example, just clicking the submit button will have access to the prices of a particular course.

This is for the purpose of collecting leads.

I saw this function on the following website (in the form on the right side): https://labpub.com.br/curso/inovacao-design-thinking-como-identificar-as-necessidades-de-seus-clientes-e-criar-solucoes-inovadoras/

Can you give me some idea, suggestion, or guide me in any way …?

Thank you very much in advance.
