PCB Antenna Issue on STM32WB55 USB Dongle

To the ST Technical Support Team:

I have a question regarding the use of the STM32WB55 USB Dongle. This board features both an onboard antenna and an IPEX antenna connector. However, the schematic indicates that the components for the IPEX interface are not populated. I have three questions:

(1) Is this connector functional as it is?
(2) Do I need to solder capacitors to it, and does ST provide soldering services? The board is already quite challenging to solder on.
(3) Does ST offer a version of this development board that comes with the IPEX antenna pre-installed?
