How to write an HTTP/2 SETTINGS frame – from server to client – in runtime agnostic JavaScript?

I’m trying to create an HTTP/2 SETTINGS frame per https://datatracker.ietf.org/doc/html/rfc7540#section-6.5 and https://datatracker.ietf.org/doc/html/rfc7540#section-6.5.1.

If I’m reading this correctly a SETTINGS frame can have zero parameters

The payload of a SETTINGS frame consists of zero or more parameters,
each consisting of an unsigned 16-bit setting identifier and an
unsigned 32-bit value.

Given an ArrayBuffer and a DataView instance in JavaScript, for example, in the console of the browser, how to write the most basic HTTP/2 SETTINGS frame – from server to client?
