Android multi-quantity purchases

hello!

i have a google play in-app product which allows multi-quantity purchase( Top 3 things in Google Play | Android @ Google I/O '21 - YouTube)
where can i find the quantity of purchases in a transaction event? ( Solar2D Documentation — Plugins | google-iap-billing-v2 | storeTransaction | transaction (coronalabs.com) )
Will there be an additional property named “quantity” or something else?

Thank you☺

While technically the new Google Billing API supports multi-quantity purchase, this has not been fully implemented into the plugin at the moment and is still limited to single purchases

Thenk you for your response☺
