Opensea plugin's cancel buy order not working

Hi, i am trying to use Moralis.Plugins.opensea.cancelOrder to cancel buy order. but getOrder function doesnot return order data of buy order. but only sell order. How can i cancel buy order? Also how can i approve (fullfill) buy order?

What wallet do you use?
