macro for an ability check

I want my macro to do a Nature check with advantage.  This is what I have: &{template:default} {{name=🌼 Searching the Area 🍄}} {{@{selected|token_name} gets a [[{1d20}]] / [[{1d20}]] on their search, potentially finding [[1t[CommonFlora]]] and [[1t[CommonFlora]]] and  [[1t[CommonFlora]]] and  [[1t[CommonFlora]]] and [[1t[CommonFlora]]]}}} How do I change the  [[{1d20}]] / [[{1d20}]] for a Nature Check with Advantage (nature_roll)
