General Help as I am new

[Draethos]

So I am new to this and I needed some help to get my app running with this plugin and I just wanted to ask basic questions atm about the plugin so that I can hopefully get it running. First of all, in the old plugin i had, i needed to do this everytime i connected """""billing.querySkuDetails(["swordskin"], "inapp")""""
but in the current plugin i cant seem to find where i need call the purchases or at least store them so that google knows which ones i need. So how do i add the available for purchase products, and where do i put them as i cant seem to find anything like that in the example code. Thank you and sorry for the trouble as i am currently running low on time.
