Site uses JS to make text appear, how can i capture that text?

Hello, so basically, a http request to a JS script, generates random options
A, B, C, D
there isn’t anywhere in the responses of the site where i can see if it’s either of those, but i can see it on the screen, how can i capture what it says on the screen, executing JS?

with a parse block,
if the site wont execute the js without actually opening it in a browser,
then try to open the page with puppeteer or selenium and put a “file write bytes” block behind it, and parse the saved file;
