How do I embed an "EVA" view display in a twig template? I installed the "Twig Tweak" module for Drupal 8

I created an "EVA" display. The view id is "contenu_relation_groupe" and the display id is "entity_view_1".

I added the following in the twig template for my nodes:

{{ drupal_view('contenu_relation_groupe', 'entity_view_1') }}


But nothing is displayed. Any idea why?

I've never managed to embed an "EVA" view in a twig template.
EVAs get added as a field with name like VIEW_ID_DISPLAY_ID. They should appear in the content variable like any other field.

If you've added your EVA to the node's display you should be able to render your EVA, with the configuration from the Manage Display screen, like 

{{ content.contenu_relation_groupe_entity_view_1 }}.
