The military leader of Wakanda, Okoye, and T'Challa's sister, Shuri, both have prominent roles in "Infinity War" as they help T'Challa and the Avengers in the fight against Thano in Wakanda. Now that Wakanda is no longer hidden, Okoye will be even more integral in protecting the nation, while Shuri — who is Wakanda's leading scientist — has her hands full spearheading Wakanda's outreach centers (we know T'Challa is having some built in Oakland).
