What are you trying to achieve:
I need to fire a Pixel, ensure the Pixel registers and make a phone call on the click of a button.

What have you already tried:

I have tried the code below:

export function button_click(event) {

// This isn't the actual URL but it looks very similar.
  let imageUrl = "https://testPixelEvent/?tag_id=01&buzz_key=tu&value=&segment_key=tu-0001&account_id=1&order=[ORDER]&ord=[CACHEBUSTER]"

  fetch(imageUrl, {
  method: 'GET'
  })
  .then(response => {
  if (response.ok) {
  console.log('Pixel fired successfully');
  } else {
  console.log('Failed to fire pixel');
  }
  })
  .catch(err => {
  console.error('Error firing pixel:', err);
  });

  // Initiate a phone call
  let phoneNumber = "+1123456789";
  wixLocation.to(`tel:${phoneNumber}`);

}
