how to transfer photos to ipad from camera using camera connection kit?

Hello everyone,

I bought a used genuine apple connection kit (but only one peace, for usb) on ebay.

I just tried to connect my camera to iPad and nothing is coming up. I would have thought so the iPad would start something automatically.

Is there a way I can try to upload photos manually? What do I need to do on iPad? Where to look? what to open?

(I have no photos on iPad yet)

(and, please, no advice how to do it using computer, as I don't have one)

Thank you for your help. 😊
