I don't think that's what OP is saying. To me, it reads like, "I'd love to know what this is, but based on the linked document and others within near proximity - I can't" which means the link requires that OP has knowledge of the frontend build world - which I will tell you is niche and disparate or that there is a big unsaid problem in this space that is non-obvious to anyone outside of it.
Curiously, both are true. Give OP some slack.
