I have bought the Reaction Force DLC and am eager to play but can't figure out how to play the new DLC on Mac.

I normally type a set command into the terminal such as the below;

open -a Arma3 --args -mod=contact -p default -no-remote

With the 'mod=??' being the descriptive part that aligns with the mods but I can't find anywhere where it tells me what I will need to type in to access the new Reaction Force DLC.

if there is anyone that is able to help me access the new DLC on mac, please do get in touch.
