Write comment on specific website using R

Hello let's have a URL to an article:

url <- "https://wiadomosci.wp.pl/tarczynski-wystartuje-w-wyborach-do-pe-wdowa-po-gosiewskim-skarzy-sie-ze-pis-chce-oddac-jej-miejsce-6355668506237057a" 

How to write a comment on this website ("Hello, world") using R?

Which package / command shall I use?

Comment bar on aforementioned website do not require login/e-mail/facebook etc. just: Comment "Napisz Komentarz" + Nick

The website is not in English but I could not find another in English without any requirements to write a comment.
