Changing a users network to the supported network

I can’t quite figure out how to change the user network to the supported network as it appears using this library I can’t access window.ethereum.

change meaning add the required network to use my website to their metamask. Any help would be appreciated thanks!

Is there a recommended way to do this ?

I solved the issue. This is how you would do it.

 useEffect(() => {
     if(active == true ) {

  if (chainId != 80001) {
    library.provider.request({
      method: 'wallet_addEthereumChain',
      params: [
        {
          chainId: '0x13881',
          chainName: 'Mumbai testnet',
          nativeCurrency: {
            name: 'matic',
            symbol: 'matic',
            decimals: 18,
          },
          rpcUrls: [
            ' https://polygon-rpc.com ',
            'https://rpc-mainnet.matic.network',
            'https://rpc-mainnet.maticvigil.com',
          ],
          blockExplorerUrls: ['https://polygonscan.com/'],
        },
      ],
    })
  }
} 

}, [active ])`

0.6.3 was the version when this worked for me. Haven’t updated the site lately as it was finished.
