OSD setup for f.port link monitoring

I want to test my R9 control link and compare it to Crossfire.
I already connected my receiver using f.port and all is working. All I’m missing is what to set up to be able to monitor the link using OSD data?

I was using LQ for Crossfire, but not sure what about R9.
I have my RSSI Type set to 3. But what element do I need to enable on my OSD screen this I do not know.
