Rename Player

I am trying to make it so after a button is clicked, it removes the generated UI and renames the character with their original name + another word or 2 at the end.

I have the functions for “GetDescriptiveName” and “RenamePlayer” but I am not quite sure how make it so it takes “GetDescripiveName”+“word” and outputs that to rename the player. Also how to tie it into the OnClicked event. Any help would be appreciated.
