Category avatar in notification email

Hello,

Could you tell please, how to display category avatar in the notification email ?

There is author blog author avatar in post.new.php, then I guess it should be possible for category avatar

<img src="/<?php echo $blogAuthorAvatar;?>" aria-hidden="true" width="64" height="64" border="0" alt="" class="center-on-narrow" style="width: 100%; max-width: 64px; height: auto; background: #dddddd; font-family: sans-serif; font-size: 15px; line-height: 20px; color: #555555;">
