Why K2(PtCl6) does not give white precipitate with AgNo3?

We know the chloride ion (Cl-) react with AgNO3 to form a precipitate of AgCl { which is the white precipitate as mentioned}.
In Potassium hexachloridoplatinate(IV) , the chloride ion is present inside the 'chordinasation sphere' . So it has now lost it's ability ionize and the complex (PtCl6) (-4) remains as such in the aqueous solution , and not dissociate individually to platinum and six chloride ions.
Since no chloride ion is formed the former white precipitate of AgCl is not formed.
