How does nodejs send a http2 request for a custom header? It's HTTP2!

although I found the http2.js package in NPM, https://www.npmjs.com/package.
, I simply wrote the get method, and there is no example of how to customize the header quota. I wonder how the gods should customize the header
look at the official node documents. I am completely confused. Uh. Please give me some advice
