How to fit Bidet Douche

[DIY2022]

Hi,

I recently ordered the below bidet douche:

I'm unsure as how to fit this and if there are additional components which will be needed to fit it? It is a mixer bidet, so will have a hot and cold feed via 15mm copper pipes. The fitting seems to want to attach to something which screws in rather than simply pushing in 15mm copper pipes into it.

FIY I am a DIY novice and unfamiliar with this sort of work.

Could somebody tell me what additional parts I will need to fit this bidet douche?

I would greatly appreciate if someone could give me a step by step guide as to how to go about fitting this bidet douche.

I have attached photos to help.
