HTML list items get hidden by scroll function instgram

I am trying to get the list of all Instagram story viewers names, The problem I'm having is that I can get all the elements in that list, How can I get all the list not only the small part that I am viewing? I am using js to get the items using the DOM to get all the profile pictures of the accounts in the list

var x = document.getElementsByClassName("_6q-tv");
x.length

I am getting The length as 17 while the story viewers are 180

I tried to do it in beautiful soup (python) but the same result was given how can I get all of them?
