Automation to Increase/Decrease Samsung SmartThings enabled AC

Currently my Samsung AC supports Setting the HVAC Mode & Setting a Specific Temperature.
BTW under New Automation’s Action, if I chose Device > Samsung AC; it only shows the option to Set the HVAC Mode. If I chose Call Service > Climate: Set temperature; there it shows option to Set a Temperature, HVAC Mode & a few others.



I have a Sonoff R5 Scene Controller. I want to use my R5 Remote’s two buttons to Increase/Decrease the Temperature of my AC.
Can someone please tell me how to do that?
