Next LS author here! I would love to hear about how your emacs experience went and what your setup/config is. My emacs skills are not the best (zero), so I've not been able to really work through any of the kinks.
I have recently gotten it working tho with vanilla emacs with eglot, as well as doom emacs (again, with eglot).
In this case, its an extension of the phrase but using the word built instead of made.
