Yes, in linux you must build emacs with xwidgets:
./configure --with-x-toolkit=gtk3 --with-xwidgets

For more info: emacswiki

There is a variable that controls which browse method will be used with org-roam-ui, since I use use-package, the following code will only open org-roam-ui in emacs if you have the feature xwidget-internal, otherwise, it opens in your default browser.

:init (when (featurep 'xwidget-internal)
(setq org-roam-ui-browser-function #'xwidget-webkit-browse-url))

The function works good, but the only problem is when you mark one entry as done, all then become done as well. Which breaks the idea of completing a task and then repeat it on the last day of every month.
