If you are talking about adding a delay between cards then add a execute code card and add the following code:

async function waitNSeconds(n) {
  return new Promise((resolve) => {
    setTimeout(() => {
      resolve()
    }, n)
  })
}

// Usage
console.log('Start waiting...')
await waitNSeconds(7000) // 5000 = 5s adjust waiting time here

Adjust the time as you see fit
