Adding RNAV to FP?

I am having the hardest time how to add a RNAV approach, with transition to my FP…I’m just not seeing a button to “add to FP”. I can bring it up, I can pin it…I just don’t see a option to add it… I know its me… I just can’t figure it out…What am I missing?

Click on the three dot menu icon, on the AIRPORT bubble in the flight plan, for the airport in question. You can add the approach (and all else) there.
