Mini dishwasher

I ordered the Cookology mini dishwasher. Can you please tell me which adapters I need to plumb into the cold water tap. The tap is stainless steel square with a rubber round at the bottom of the tap. I can send you some photos of the tap. I’ve been searching and searching over several days but there are so many adapters which I don’t know which one fits? I would also like to fit a diverted valve so that I don’t have to keep taking the adapter on and off. I really hope you can help me? Thank you. Carolina
