<ConnectButton
  client={client}
  accountAbstraction={{
    chain: sepolia,
    sponsorGas: true,
  }}
/>;

<ConnectButton
  client={client}
  auth={{
    isLoggedIn: async (address) => {
      console.log("checking if logged in!", { address });
      return await isLoggedIn();
    },
    doLogin: async (params) => {
      console.log("logging in!");
      await login(params);
    },
    getLoginPayload: async ({ address }) =>
      generatePayload({ address }),
    doLogout: async () => {
      console.log("logging out!");
      await logout();
    },
  }}
/>;
