sitelink searchbox schema in pages

[dvd2org]

hi this is one of my website url inspection. ass u see in result there is sitelink searbox schema. all of my pages include this schema.

Google recommends only one SearchAction for a website and an optional another, only if it supports an app search. Hence, the SearchAction should be pointed to your homepage even if the Schema appears on all your web pages.

is this true?

if this is wrong and not standard, how can i fix it. i have SEO Audit module for my website.
