The 100pf is only required when your design is planned to support both an SMA connector and an antenna.
If the board only supports an SMA connector, there is no need any additional component.
If the board only supports an antenna, then you need a matching network in between the IPD and the antenna.

Find below the link of the gerber file for the reference boards with the IPD:

You can also have a look at the application note AN5165 ‘Getting_started_HW_RF_development’ for the STM32WBxx board design guidelines
and the datasheet of the IPD MLPF-WB55-01E3 to follow for a correct implementation of the IPD.
