How to access the JSON file that stores all user info?

Hi I am trying to create a web app and I require to scrape the information from this website..

https://getbiib.com/events/104

I would like to access the JSON API that contains all the runners(4347 entries) from this webpage. But I could only get the JSON file of what is displayed in front of me only. Here is an example of the JSON URL I only managed to obtain.

https://getbiib.com/events/104/individual_rank.json?category_type_id=44&draw=1&columns%5B0%5D%5Bdata%5D=rank&columns%5B0%5D%5Bname%5D=&columns%5B0%5D%5Bsearchable%5D=true&columns%5B0%5D%5Borderable%5D=false&columns%5B0%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B0%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B1%5D%5Bdata%5D=display_name&columns%5B1%5D%5Bname%5D=&columns%5B1%5D%5Bsearchable%5D=true&columns%5B1%5D%5Borderable%5D=false&columns%5B1%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B1%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B2%5D%5Bdata%5D=steps_count&columns%5B2%5D%5Bname%5D=&columns%5B2%5D%5Bsearchable%5D=true&columns%5B2%5D%5Borderable%5D=false&columns%5B2%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B2%5D%5Bsearch%5D%5Bregex%5D=false&start=0&length=100&search%5Bvalue%5D=&search%5Bregex%5D=false&_=1626617902103
