Note that the second USB-C port shield may fling off of the frame when you detach it. You can place a finger on the shield to prevent it from flinging.

Slide one tine of a pair of pointed tweezers under the other side of the shield's edge closest to the left speaker.

Lift up to completely detach the edge from the frame.

Remove the second USB-C port shield from the frame.

If the shield isn't completely detached from the frame, pry up additional areas on the edges of the shield.
