I fly Xplane 11 and usually the TBM900 or King Air 350. I don't have any AI airplanes added and these days I don't seem to be getting any traffic input to TCAS. I'm also not sure if I can see other planes around me, been very empty on last few flights. I used to get other airplanes but they may have been just generated AI since I had some of those enabled before...
So when I install Pilotedge client, do the CSL models come with it automatically or is there something else I should do in order to have a nice set of models? Is there a good addon pack you recommend? I'm getting prepared for the Oshkosh and want these basic things to work properly

Is there anything I need to do in order to have traffic on TCAS?
Thanks!
