Doesn't seem to work. Could you make a quick video tutorial? I would really appreciate it

same doesn't seem to work anyone fixed the script? I get error:

VM84:15 Uncaught TypeError: postCommentsList.promise is not a function

The script does not work since 2021 - it is kept here only for historical purposes.
LinkedIn removed JQuery dependency from it's app, so we lost the ability to easily interact with the app and manipulate the DOM.
If you need to automate tasks or simulate navigation, search for Scrapping and/or E2E - BeautifulSoup, Selenium, Cypress, etc.
