Powering the Sigma with the JST PH2.0-8Pin

I am planning to integrate the LattePanda Sigma into an autonomous mobile robot, necessitating the utilization of the JST PH2.0-8Pin connector for power supply. However, I am encountering difficulties in procuring the appropriate connector. Could you kindly provide me with the relevant part number or any other pertinent information that would facilitate the acquisition of the correct connector?
