Set reply-to email in Mailchannels api request

Is there a way to set a reply-to email on my mail send worker? People fill in a form and set their email, I then send the form to myself and set their email as a mailto link. I would like to set a reply-to header instead. The relevant code so far looks roughly as such:

let sendRequest = new Request("https://api.mailchannels.net/tx/v1/send", {
method: "POST",
headers: {
  "Content-Type": "application/json"
},
body: JSON.stringify({
  personalizations: [
    {
      to: [{ email: "info@example.com" }]
    }
  ],
  from: {
    email: "web-contactus@example.com"
  },
  subject: `Contact Us - ${form.lname}, ${form.fname} (${form.subject})`,
  content: [
    {
      type: "text/html",
      value: `<h2>Subject: ${form.subject}</h2>
                        
                        <p style="background-color: lightgray; padding: 10px; max-width: 1250px;">
                            ${form.message}
                        </p>
                        
                        <h2><strong>Email: <a href="mailto:${form.email}">${form.email}</a></strong></h2>`
    }
  ]
})
});

let sendRequest = new Request("https://api.mailchannels.net/tx/v1/send", {
method: "POST",
headers: {
  "Content-Type": "application/json"
},
body: JSON.stringify({
  personalizations: [
    {
      to: [{ email: "info@example.com" }]
    }
  ],
  from: {
    email: "web-contactus@example.com"
  },
  subject: `Contact Us - ${form.lname}, ${form.fname} (${form.subject})`,
  content: [
    {
      type: "text/html",
      value: `<h2>Subject: ${form.subject}</h2>
                        
                        <p style="background-color: lightgray; padding: 10px; max-width: 1250px;">
                            ${form.message}
                        </p>
                        
                        <h2><strong>Email: <a href="mailto:${form.email}">${form.email}</a></strong></h2>`
    }
  ]
})
});

From the Mailchannels docs, https://api.mailchannels.net/tx/v1/documentation, there's an object on the personalizations array called reply_to which you can set, with the same properties as from/to
