How can I add a product review form to a page template?

Hello,

I wish to have a dedicated page for customers to leave their product reviews. However I can only add Product Reviews blocks and sections to product or collection pages. That helps me for two reasons: to let users fill the form only if they’ve purchased the item + to send the direct link automatically seven days after purchase.

I have tried to add it via custom code, in the json file of the same page. That doesn’t work: the App section shows up, but the block has disappeared.

How can I add a Product Review form to a page template?

Thanks in advance.
