Etherscan has no support for network sepolia with chain id 11155111 - solidity

Question

I am trying to verify my deployed contract from truffle and getting "Etherscan has no support for network sepolia with chain id 11155111" error. So I am working with Etherscan and I deployed my contract on sepolia testnet.
How can I solve this problem?
My truffle-config.js
const apikeys = require("./chains/apikeys");
const keys = require("./keys.json");
module.exports = {
plugins: ["truffle-plugin-verify"],
api_keys:{
etherscan: "myApiEtherScan"
},
contracts_build_directory: "./public/contracts",
networks: {
development: {
host: "127.0.0.1",
port: 7545,
network_id: "*",
},
sepolia: {
provider: () =>
new HDWalletProvider(
keys.PRIVATE_KEY,
keys.INFURA_SEPOLIA_URL,
),
network_id: 11155111,
gas:5221975,
gasPrice:20000000000,
confirmations: 3,
timeoutBlocks:200,
skipDryRun: true
}
},
compilers: {
solc: {
version: "0.8.16",
settings: {
optimizer: {
enabled: true, // Default: false
runs: 1000 // Default: 200
}
}
}
},
};

Plugin truffle-plugin-verify doesn't have Sepolia chain support
I added the sepolia api url and etherscan url to constants and it works
const API_URLS = {
...
11155111: 'https://api-sepolia.etherscan.io/api',
...
}
const EXPLORER_URLS = {
...
11155111: 'https://sepolia.etherscan.io/address',
...
}
