Connecting an external Antenna to the Taiyo Yuden EYSHSNZWZ BLE Module using Nordic’s nRF52832 SoC - pin impedances cannot be found?

I am working on integrating an external antenna with the EYSHSNZWZ BLE module from Taiyo Yuden, which uses Nordic’s nRF52832 SoC. The biggest problem is that I cannot confirm the antenna pins impedances. Can I assume it is 50-ohm impedance, as I believe should be expected with the nRF52832 ? And if so, should I connect the antenna directly to the BLE module's RF pins (Pin 11 for OUT_ANT and Pin 12 for OUT_MOD)?

Thanks in advance for your insights!Taiyo_Yuden-EYSHSNZWZ-datasheet.pdf
