How to Set RSSI in Copter V4.0.3

There is so many RSSI parameters in the full parameters list
But I cannot see it in Mission Planner full parameters list

Is it only me or it was removed? the only one that shows for me is RSSI_TYPE

I want to setup the rssi using the RSSI function in my Taranis radio… I just updated from version 3.5 where it was possible…
Any help will be much appreciated
