Filter for language when using graphQL
You'll want to use siteId for this.
query {
    entries (section: &quot;newsIntranet&quot;, siteId: &quot;2&quot;) {
        title
        postDate
        expiryDate
        contentText
    }
}

Swap out &quot;2&quot; with whatever the siteId of the French site is on your system.
