Custom Tab Doesn’t Show Custom Content – Only displays products ?

Hi,

This code only shows a “new tab” but does not show the content set in the file store/wcfmmp-view-store-newtab.php

<?php 
    echo "Hello World "; 
?>

When clicking the Tab it shows products only ? Can you please help to provide the correct code to render the content in the php file store/wcfmmp-view-store-newtab.php
?
