Xiaomi miot call service params

Hi, I installed the miot xiaomi integration looking for control my new Vacuum Mop 2S.
I can see all entity and start, stop from lovelace but I can’t undestand how to select a specific command via service action. I mean I can start or stop but I want to select a single room: (here an example where 10 params is selected but how to send numer or rooms too?)

service: xiaomi_miot.call_action
data:
  entity_id: vacuum.ijai_v19_7513_robot_cleaner
  siid: 2
  aiid: 7
  params: 10
 
 throw: true
