Improve asking users to change network modal for MM wallets

[creed-victor]

Metamask now has a feature which allows dapps to add new network and ask for network change if user is in the wrong one:

window.ethereum.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0x38',
    chainName: 'Binance Smart Chain',
    nativeCurrency: { name: 'BNB', symbol: 'BNB', decimals: 18 },
    rpcUrls: ['https://bsc-dataseed.binance.org/'],
    blockExplorerUrls: ['https://bscscan.com/']
  }],
})

Regarding to the documentation (https://docs.metamask.io/guide/rpc-api.html#other-rpc-methods), this method should be called only after some user action (such as a button click). What is your proposed flow @t-z-u ?
