iPad Air LTE Teardown Step 10. SIM Card Tray flex Cable Connection

How do you connect the SIM Card Tray flex Cable Connection of the iPad Air LTE back onto the board? Do you just place it over the connection and use the adhesive to hold it together or the cable end needs to click in in a particular way.

The same question applies to the flex cable next to it attached to the screen.

Thank you for the answer. But my question is titled iPad Air LTE Teardown Step 10''. Which means I have already seen the Teardown guide. And on this guide it doesn't show how to disconnect nor reconnect these two cable flex connectors (What I need to do is reconnect them for my IPad is already torn down): The SIM CARD'S flex cable and the one beside it attached to the Screen. The question is: Do you just place the end metal of the connectors on the metal below and hold them down with the adhesive or they have to clip into the part below in a particular way? Please read my question attentively, I am not talking of the other flex cables at the top attached to the screen with metal plated onto them and which clip easily. I am talking of the SIM CARD flex cable and the third flex cable attached to screen which both have a plastic adhesive over them.
