puppeteer overridePermissions clipboard-read not working on createIncognitoBrowserContext() - node.js

Question

The following code is viable for reading the clipboard in headless/headfull:
var context = await client.defaultBrowserContext();
await context.overridePermissions('http://localhost', ['clipboard-read']);
page = await browser.newPage();
await page.goto( 'http://localhost/test/', {waitUntil: 'load', timeout: 35000});
// click button for clipboard..
let clipboard = await page.evaluate(`(async () => await navigator.clipboard.readText())()`);
But when you later start incognito its not working anymore:
const incognito = await client.createIncognitoBrowserContext();
page = await incognito.newPage();
and you get:
DOMException: Read permission denied.
I currently try to figure out to combine both.. Anybody know how to set overridePermissions inside of the new incognito window?
Please notice I do not want to use the incognito chrome arg at the start. I want to manually create new incognito pages inside of my scripts with correct overridePermissions.

I am having the very same issue. Here's a minimal reproducible example.
Nodejs version: v16.13.1
puppeteer version: puppeteer#14.4.1
'use strict';
const puppeteer = require('puppeteer');
const URL = 'https://google.com';
(async () => {
const browser = await puppeteer.launch();
const context = browser.defaultBrowserContext();
context.overridePermissions(URL, ['clipboard-read', 'clipboard-write'])
const page = await browser.newPage();
await page.goto(URL, {
waitUntil: 'networkidle2',
});
await page.evaluate(() => navigator.clipboard.writeText("Injected"));
const value = await page.evaluate(() => navigator.clipboard.readText());
console.log(value);
})();
