We know from The Avengers that Loki uses his Scepter (which houses the Mind Stone) to control the free will of Clint Barton & Erik Selvig.
Vision had the Mind stone with him all the time. Why didn't he use it to alter the minds of Black Order, or Thanos when Thanos held him during the end of Avengers: Infinity War?
Did Vision or any other Avenger not know how to use it?
