const metamaskConfig = metamaskWallet({ ... });

// override metadata = "..."; // change the name
metamaskConfig.meta.iconURL = "..."; // change the icon
metamaskConfig.meta.urls = {
// change urls to download the wallet on various platforms
android: "https://...",
ios: "https://...",
chrome: "https://...",
firefox: "https://...",

// override connection UI
metamaskConfig.connectUI = MetamaskConnectUI; // react component

// custom selection UI
metamaskConfig.selectUI = MetamaskSelectUI; // react component

// custom logic to check if the wallet is installed or not
