why do I have xwayland running on my ubuntu server and how to remove it

Question

I notive that xwayland is running on my ubuntu 20 server and I don't understand why. Here are all the things I have install with "apt-get install"

libmagickwand-dev libcurl4-gnutls-dev libcurl4 libcurl4-openssl-dev libcurl4 libcurl4-openssl-dev libpq-dev certbot python3-certbot-nginx jpegoptim optipng pngquant webp wkhtmltopdf
imagemagick

Is there anyway to find how it xwayland was installed?

Also I would like to know how to remove it cleanly and to remove all other useless "graphic" things that could have been installed too.

thanks
