Can I change the page of a Custom Post Type slug?

Custom post types can have a post type archive, which displays all posts of that type. In your post type registration code, it’s controlled by the has_archive argument, which is now currently false. Change it to true, or give it a string value to set it to something specific other than your post type slug.

"has_archive" => "kennisbank",
