Template file missing

Hi

I'm trying to feed in a single product to a page using;

<?php perch_shop_product('lifetime-membership-eurmed01', [
    'template' => 'membership.html'
]);?>

But nothings showing... perch_shop_product('lifetime-membership-eurmed01') works with the default template. Looking at debug, I'm getting;

Template file not found: /Volumes/FFD Web Work/EuroMed/root/perch/addons/apps/perch_shop/templates/shop/membership.html

There is a membership.html in perch/templates/shop/products/ - Which is where I thought it should go? But the debug isn't looking in the products folder, its looking in the shop folder... plus its defaulting back to the templates in the app folder.
