Web3Api with local chain (providerUrl)

Hi, i’ve read in the documentation that the Web3Api cannot be used with local chains

Local Dev Chain (Ganache, Hardhat) doesn’t work currently with Web3API.

And im seeing that Ivan said that is not posible in this forum

But i see this param ** providerUrl** available to all Web3Api calls, and the description says:
“web3 provider url to user when using local dev chain”
So i wonder what is the purpose of the param then?
