How to configure sma connection with fpga pins for reading external ttl pulses

Hi, I’m fairly new to FPGA design and am stuck on how to configure the SMA connections. I just want to read in pulses from the J15 Rx lane to increment a counter as part of my project. I realized I can’t connect the pin H2 as an input wire for my module by using set _roperty in the xdc file. What construct do I need to use to correctly read from sma J15? I’m developing the firmware using Vivado ML edition 2023.2 and not using frontpanel at the moment. I was reading other forum posts and they seem to indicate I should use Vivado’s transceiver wizard. Thank you for any guidance and help.
