User Activity

Hi All,We would like to limit dashboard to only specific CI classes, Let me know how it can be done.
I need to trigger survey from a portal widget, Let us know if anyone has worked on similar requirement. Tried using below code, but receiving error. new SNC.AssessmentCreation()).createAssessments('62d95a812f06011028f12f2ef699b611',"",usr)
Can we call subflow or flow from a ui action. If yes let me know how to call.
