Is SSI currently working with nodejs projects?

I followed this steps : https://docs.wappler.io/t/server-side-includes-ssi/2864 except that the file i include is a html file.
On Wappler design editor i see the included component. But when server is running and i go to the page on my browser i don’t see the included component. I only see < ! --#include file=“components/header.html” - - > in the code inspector. Do you currently manage the rendering of the included file on server? Or what do i need to do in order to see my rendered component instead of the comment which is supposed to be used on server side to render it? Of course i can easily do that on server side, but i don’t think it’s the goal here. Thanks in advance.
