Hi everyone, hope you are all well

I am new here and I need some guidance on my Birdy.
Is any expert able to guide me or direct me to a video on how to remove the Shift cable and housing for a Birdy? I am stuck not being able to remove the black attachment that is connected to the rear part of the birdy where you are able to fold (near the release clip)? I am not able to replace a new shift cable and housing in this case. Thanks for the help in advance!
