How to add a custom network for solana?

[goodbingo]

Hi Everyone,
I'm adding a custom network for solana, but it's not working, it still return default rpc url. Or how to increase the reown cloud api limits? Thanks inadvance!

Here is my code:

import { solanaWeb3JsAdapter, wagmiAdapter, networks, projectId } from './config/index'
import { defineChain } from '@reown/appkit/networks';

const customnetwork = defineChain({
  id: '5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp',
  caipNetworkId: 'solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp',
  chainNamespace: 'solana',
  name: 'customnetwork',
  nativeCurrency: { name: 'Solana', symbol: 'SOL', decimals: 9 },
  rpcUrls: {
    default: {
      http: ["https://warmhearted-wispy-film.solana-mainnet.quiknode.pro/9272730xxx"]
    },
  },
  blockExplorers: {
    default: { name: 'Explorer', url: 'https://explorer.solana.com' },
  }
})

// Initialize AppKit
createAppKit({
  adapters: [solanaWeb3JsAdapter],
  networks:[customnetwork],
  projectId,
  themeMode: 'light',
  features: {
    analytics: true // Optional - defaults to your Cloud configuration
  },
  metadata: {
    name: 'AppKit Vue Example',
    description: 'AppKit Vue Example',
    url: 'https://reown.com/appkit',
    icons: ['https://avatars.githubusercontent.com/u/179229932?s=200&v=4']
  },
  themeVariables: {
    '--w3m-accent': '#000000',
  }
})
