8 – How to create a template for the product variation?

I have enabled debugging in the drupal service file. My product type display the rendered entity of the RSS view in the variation field. When I inspect a product page no model for the variatin is offered.

I followed the documentation :

https://docs.drupalcommerce.org/commerce2/developer-guide/products/displaying-products/theme-product#theming-product-variations

My product type has the machine name “produit” and the display “rss”. I created a template :

commerce-product-variation--produit--rss.html.twig

It does not work, it seems to be ignored.
