Example for connecting to Polygon Mumbai test network please? ☺️

[webhype]

I was unable to google one example to connect via ethers.js to polygon-mumbai network on Infura. Do you guys have any?

By trial and error, I found that this doesn't crash, but doesn't quite "work" either (later steps don't work, which could be for all kinds of reasons, but trying to rule out a "bad" connection to Infura):

const provider = new ethers.providers.InfuraProvider(null, {
	network: "polygon-mumbai",		// this wasn't even documented but apparently makes it not crash
	projectId: "0x1234567890abcdef",
	projectSecret: "0xfedcba9876543210"
});

Am I connecting correctly to the polygon-mumbai test network?

What about connecting to polygon-mainnet? Is that correct?

const provider = new ethers.providers.InfuraProvider(null, {
	network: "polygon-mainnet", 	// this wasn't even documented but apparently makes it not crash
	projectId: "0x1234567890abcdef",
	projectSecret: "0xfedcba9876543210"
});

The ethers.js documention is so ultra brief and poor in rich, real-world examples of various non-Ethereum, non-mainnet examples (what's up with "homestead"? 😃 Why not call it "mainnet" if that's what you mean? lol, took me hours to figure out).

Not trying to be snarky, it's an awesome library, but just a few extra lines, with real-world examples, would go a long way (this message goes equally to Infura). Thanks! ❤️

From packages/providers/src.ts/infura-provider.ts in this repo network = "matic" corresponds to polygon mainnet and network = "maticmum" corresponds to the mumbai testnet although the docs haven't been updated to reflect this. I can submit a quick PR

hey, stupid question - i know. but where can i get the minimizer-version for that release :-()

I probably won't include a Mumbai specific example, but the changes in #2242 will go up soon, which should help. :)

Merged the changes in #22242.

Thanks! :)
