Requête MongoDB avec conditions sur tableau

Bonjour à tous, je cherche à écrire une requête qui va me sortir uniquement les monnaies ayant un "available" > 0.

Pour l'instant je ne trouve pas comment poser des conditions sur le tableaux "currencyarray"
Code:
var profil = profil.find({"plateforme": "myexchange", "arraycurrency": Available : {$gt: 0}});
J'ai bien trouvé plusieurs syntaxes, sans résultat probant pour mon cas

Sur le jeux de données ci-dessous (l'ensemble des datas à été modifié de façon aléatoire):
