How do I control comments scrolling?

Hello, We have our own button to type notes, and when I type notes, the scroll is at the top, so if the notes are long, I'd like to lower them to the bottom. Currently, scrolling is at the top, blocking some comments.

We're typing notes with the code below, what should we add to scroll down to the bottom when typing?

let comment = "comment";

client.set('comment.text', comment);

let zendeskTextbox = document.getElementsByClassName('ck-content');

zendeskTextbox.scrollTop = zendeskTextbox.scrollHeight;
