Help required with drivers external door handle

[macafee2]

I am trying to remove part of the external door handle for a member but am stuck.
Towards the door edge/left of the actual handle is a chrome plastic? shroud. I understand that inside the door a small clip needs to be slid towards the back of the car to release this shroud.

Do I need to have the window down to be able to see and access this clip?

thank you
