can we get the value of measurement through onResultsChange —instead of Type?

with onResultsChange:

import SpeedTest from 'https://cdn.jsdelivr.net/npm/@cloudflare/speedtest';
const engine = new SpeedTest();
engine.onResultsChange = (payload) => {

console.log(payload, "this working");

};
getting:

{
type:"latency"
}

but is there someway so i get value of measurement —
something like:

{
"phase": "during idle",
"ttfb": 56.80000001192093,
"serverTime": 35,
"serverTimeDelta": 3.224999964237213,
"ping": 18.575000047683716
}

Start with the SpeedTest onResultsChange callback and inspect the payload currently reported as {type: "latency"}; compare it with the measurement fields shown in the issue. Determine which values are available at callback time and expose the intended measurement data through the callback, then verify the callback output matches the documented shape.
