Set accessibility focus after button click

Hi all,

I am trying to figure out how one would get the accessibility cursor to change focus to an element after a button click. For example when I press a button in my app that is hiding content I want to focus on those new elements that have recently become visible after a button click. Im aware of tab index in XF 4.0, but my understanding of TabIndex is that it only sets the order in which the focus is supposed to follow. I want to set the accessibility cursor on an element that has just been made visible to the user, and then set the order on those new elements. Is anyone aware of how I could accomplish this?

Thanks!
