How does contextProcessModels property of a!queryProcessAnalytics() function wor

How does contextProcessModels property of a!queryProcessAnalytics() function work?

My a!queryProcessAnalytics() function works great below when using contextProcessModels, but when I try and switch to contextProcessIds to display just the current process, it returns nothing. So then I backed up and just tried to hard-code the process ID that I want which is 6400, and that doesn't work. I tried using the processId variable and toInteger(6400) but no luck. What gives?

How is the contextProcessIds used correctly to return just those process IDs (pp!id) and can you show an example?

Thanks much!

local!report: a!queryProcessAnalytics(
report:cons!eOff_TASKS_GRID,
/* contextProcessModels: cons!EOB_MAIN_PROCESS_MODEL, */
           contextProcessIds:{tointeger(6400)}
          
           /*
contextProcessIds:
           contextProcessModels:cons!eOFF_MAIN_PROCESS_MODEL
           contextProcessIds:6400,
           ri!processId,*/
