Changing default Message body with function

Hello,

I am working on a multi-site website for my company that has some automatic functions happen when a theme is activated to help speed up my workflow. All templates/websites share the same contact form. Each time I create a new site and create a new form, I have to repeatedly update the Form and the Message body with the content I need. I currently have a function that changes the default Form content that works great. However, I cannot modify the default Message body for the life of me. All fields come back blank on my end. Here is my current code:

function mod_contact7_form_content( $template, $prop ) {
  if ( 'form' == $prop ) {
    return implode( '', array(
        '[text* your-name placeholder "Name"]',
        '<div class="row mt-3 mb-3">',
        '<div class="col-12 col-md-6">',
        '[email* your-email placeholder "Email"]',
        '</div>',
        '<div class="col-12 col-md-6 mt-3 mt-lg-0">',
        '[tel* your-phone placeholder "Phone"]',
        '</div>',
        '</div>',
        '[select* options "Choose Option" "Service" "Maintenance" "Installation"]',
        '[textarea your-message x4 class:mt-3 placeholder "Explain Your Issue"]',
        '[submit class:btn-block class:btn-tempstar class:mt-3 "SEND YOUR MESSAGE"]',
    ) );
  } else {
    return $template;
  } 
}
add_filter('wpcf7_default_template', 'mod_contact7_form_content', 10, 2);

function mod_contact7_form_body( $template, $prop ) {
  if ( 'mail' == $prop ) {
    $template = array(
        'body' => array (
        'Your contact information is as follows:',
        'Name: [your-name]',
        'Email: [your-email]',
        'Phone: [your-phone]',
        'Needed Request: [options]',
        'Message: [your-message]',
        'Be sure to follow up soon!',
      ) );
  } else {
    return $template;
  } 
}
add_filter('wpcf7_default_template', 'mod_contact7_form_body', 10, 2);

Can you help with this?

Thanks
