Show Cause Notice From Customs For Ordering Sex Toy Last Year (Ali Express)

I know this similar headline here, but I had ordered a sex toy from Aliexpress in June of 2019, which got held up at customs last October when it arrived. I don't have details of the purchase from the app, as history has been wiped. I only have emails of the order ID and Tracking number, and when it was stopped at customs. I don't even know which product, and I only know from my account statement that it cost around 2300 Rs/-. A couple of Days ago I received a Show Cause Notice under Sec 124 of Customs Act from the Office of Deputy Commissioner of Customs, Chamrajpet, Bangalore. As the other people previously posted, I had no idea that it was illegal to buy(or import as they term) sex toys into India, and do not want it now. In the notice they have only mentioned it being 'liable for confiscation' and there is no mention of a penalty or fine to be imposed, along with whether I want to be heard in person, which I do not. Do I need to reply, and if so, will I be fined a penalty?
