Variant CeramicSpeed OSPW RS ALPHA ramienko prehadzovačky pre Shimano 9250/8150, čierna

Hello, I have a road bike equipped with a Shimano Dura-Ace Di2 RD-R9250, 12-speed electronic set. I would like to make sure that this product is suitable for my set. I would also like to ask if when purchasing this CeramicSpeed ​​OSPW RS ALPHA derailleur hanger, the CeramicSpeed ​​UFO Factory Optimized KMC chain, 12-speed, 126 links must also be used, or can a classic chain, such as Shimano XTR, be used.
Thank you for the information.
