[Drupal 8] Changing the template of a view which is my front page

Hi.
My front page is made by a page which comes out of a view. That view page has /node for path.
I’m using a “child” theme of bartik.
I’d like to modify the template of that page in order to have only the “content” zone with my view ; no sidebar, etc, on that front page.

Can’t figure wich template I should modify.

Any idea, help, welcome

Best regards
D
