grip-mode doesn't open an external browser, instead open another buffer

I was under the impression that the default behavior would be to open an external browser, like the first screenshot. Is there a way to make it open an external browser? I tried setting the default browser like the readme instructed, but that didn't fix it

To be clear,

1. Are you using emacs with --with-xwidgets?
2. Did you try (setq grip-preview-use-webkit nil) if you are using xwidget?

1. Yes. This is the output of emacs -nw -q --batch --eval '(message system-configuration-options)':

I'm using this AUR package because I'm on Wayland. The name xwidgets makes it sound like that might be a problem, but that's just a though from someone who doesn't know much about the deep inner workings of Linux :)

2. I did not, but adding that option fixes it! Would it be possible to add that to the readme? It currently implies that opening the browser is default behaviour, because according to the readme you need to assign the variable to t to make it open the buffer

I believe it has already been in README. You may misunderstand.
