How to select an element of type aria-controls

IhavetriedinallwaystoexecutetheWedDriver'sClick()methodonthebuttonelement

//*[@id="pedigree-controls"]/div[2]/div/div/button (destacado em azul (dropbtn))

However, for some reason, perhaps because it is an aria-controls and contain a span class I can not.

Does anyone know of any way to get to this element?

Driver.FindElement(By.CssSelector("li[aria-controls='pedigree_select']")).Clicks();
