Once an application is connected to Martian wallet via connect method, an app can request the user to sign and submit the transaction using window.martian.signAndSubmitTransaction()and it will return a Promise that resolves when the user accepts the request and reject (throw when awaited) when the user declines the request or request is not valid/fails. It takes one parameter listed below

const response = await window.martian.connect();
const sender = response.address;
const payload = {
