HardhatError: HH303: Unrecognized task verify: verify

I run yarn hardhat command, and it showed that I have a verify task
AVAILABLE TASKS:

accounts Prints the list of accounts
check Check whatever you need
clean Clears the cache and deletes all artifacts
compile Compiles the entire project, building all artifacts
console Opens a hardhat console
coverage Generates a code coverage report for tests
flatten Flattens and prints contracts and their dependencies. If no file is passed, all the contracts in the project will be flattened.
gas-reporter:merge
help Prints this message
node Starts a JSON-RPC server on top of Hardhat Network
run Runs a user-defined script after compiling the project
test Runs mocha tests
typechain Generate Typechain typings for compiled contracts
verify Verifies contract on Etherscan

I required "@nomiclabs/hardhat-etherscan" in hardhat.config.js

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()
require("@nomiclabs/hardhat-etherscan")
task("accounts", "Prints the list of accounts", async () => {
const accounts = await ethers.getSigners()

for (const account of accounts) {
    console.log(account.address)
}

})
const GOERLI_RPC_URL = process.env.GOERLI_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
defaultNetwork: "hardhat",
networks: {
goerli: { url: GOERLI_RPC_URL, accounts: [PRIVATE_KEY], chainId: 5 },
},
solidity: "0.8.8",
etherscan: {
apiKey: ETHERSCAN_API_KEY,
},
}

I have "@nomiclabs/hardhat-etherscan": "^3.1.6" in package.json
{

}
}

How can I do

@monzzzz Make sure this does not have any space between verify:verify, it is the verify function which verifies the contracts (inside the utils folder).
