Equivalent to app mode? (Dedicated browser instance for a page)

Hey,

I know how to open a web page in a new nyxt window from a shell script:

nyxt -r -e '(make-window (make-buffer :url "https://kagi.com"))' -q

but, is it possible to emulate something like Chrome's app mode, where "installed" web pages open in their own instance? Or, at least open the page in a new nyxt instance without all of the open buffers from the main instance?

I don't know about Chrome's app mode, but I think you need to understand whether you'd like to open a new URL in an existing Nyxt instance or a new one. The latter can be achieved via nyxt https://en.wikipedia.org/wiki/Tomato.
