How to use "Toggle analysis" in Sabaki with PhoenixGo?

Hi, 

when I try to set engine of phoenixgo as analyzer in Sabaki v.0.52.0, a prompt of warning comes to show that, "The select engine does not support analysis.". However, it works OK for both of leela-zero and sai routines. So could you please advice if there is anything possible to be modified to make this analysis feasible for phoenixgo?
