Adding a hyperlink to an inline image on Google Appscript

I have the below code which adds an inline image to an email that gets sent from the google sheet. I am working on adding a hyperlink to the inline image. Any guidance on how to achieve this would be appreciated!

    var pwcURL2 = DriveApp.getFileById("1C56M6DeZCm9IK5K26Z_ZYNLMb8rdqB4a").getBlob();

    var pwcblob = UrlFetchApp
                            .fetch(pwcURL)
                            .getBlob()
                            .setName(pwcblob)

//Some more lines of code in the middle which I have skipped as they are not relevant to the question being asked here

    bodypwc = "<img src='cid:pwc' style='width:24px; height:16px;'/>" + bodypwc;
    MailApp.sendEmail({ 
      to: currentEmail,
      subject: subjectLine, 
      body: messageBody,
      attachments: [liabilityWaiver1,liabilityWaiver2],
      htmlBody: messageBody+"<BR/><BR/>"+"<img src=\"cid:sampleImage\">",
      inlineImages: {sampleImage: pwcURL2}
    });

• You want to add the hyperlink to the inline image of Gmail.
• You want to achieve this using Google Apps Script.

In this case, how about adding the hyperlink to <img src=\"cid:sampleImage\">?

Modified script:

When your script is modified, it becomes as follows.

function myFunction() {
  var url = "https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.png";  // Sample image
  var image = UrlFetchApp.fetch(url).getBlob();
  var currentEmail = "###";  // Please set the email address.
  var subjectLine = "sample subject";  // Please set the subject.
  var messageBody = "sample message body";  // Please set the email body.
  var urlForInlineImage = "https://stackoverflow.com/q/60689970/7108653";  // Please set the URL you want to add to the inline image. Here, the URL of this question is used as a sample URL.
  
  MailApp.sendEmail({ 
    to: currentEmail,
    subject: subjectLine,
    body: messageBody,
  //    attachments: [liabilityWaiver1,liabilityWaiver2],  // Here, as a sample case, no attachment files are used.
    htmlBody: messageBody+"<BR/><BR/>"+"<a href=\"" + urlForInlineImage + "\"><img src=\"cid:sampleImage\"></a>",
    inlineImages: {sampleImage: image}
  });
}

When you run the script, you can see an email including the inline image with the hyperlink.
