Use the tip of a spudger to lift up the locking tab on the ZIF connector.

Use tweezers, or your fingers, to grip the blue pull tab on the interconnect cable and disconnect it.

During reassembly:

Inspect the ends of the cable and the ZIF connectors for any remaining coating that could prevent a good connection.

Peel off the coating, heating the cable and the ZIF connector when the coating becomes too brittle.

It doesn't have to look pretty! You just need to remove enough coating to have the cable sit properly in the connector.
