We have a view, custom_view, that was created to be displayed on a page that is of the basic page content type. The basic page content type is using the Default View mode and has a taxonomy term, custom_tag.
Initially we thought about adding the block to the theme block layout, but that does not provide what we need. The custom_view should only be visible on the basic page content type for the Default View and not others.
How do you add Views to a View Mode?
The view has a contextual filter so it takes in the current language and it takes in the value of the custom_tag since it is present on the basic page content type.
