Found a solution. I had to create a new template in the Theme section. Involves a copy-pasting a code from an existing template and changing the name of the template created.
Go to your Shopify store > Online Store > Actions > Edit Code > Click ‘Add new Template’ (make sure to select Liquid under template type) and copy the code below (works for Impulse Theme, not sure about other themes):
{% section ‘product-template’ %}
{% section ‘product-[insert theme name]-xxxx-xxxx-template’ %} <If your template name is multi-worded make sure to use ‘-’ between each work (without the quote marks)
{% section ‘product-recommendations’ %}
{% section ‘recently-viewed’ %}
{% if collection %}
{% endif %}{% render ‘judgeme_widgets’, widget_type: ‘judgeme_review_widget’, concierge_install: false, product: product %}
