Yeelight integration with Mi Home

Hello. I got a Mijia EU Gateway and some sensors with it. I have a few Color 2 and filament bulbs from Yeelight. I can only pair the gateway to the German server, but then my filament bulbs don’t show up in the Mi Home app. I just don’t get why the Mi Home app does not expose devices that are already paired to the SAME server with Yeelight app. I bought everything through Xiaomi official partner stores in Lithuania. Expected everything to work together because all of the items are from the same ecosystem. Any recommendations on how to get everything working together?
