How can I set up a Character Selection Menu for an Interactive Visual Novel?

Hello! I started using unreal a few months ago, and was asked to develop a fairly simple interactive visual novel. The player, after selecting a character, will be able to choose three environments in which dialogues and choices leading to different endings will take place.
Having no experience I used and modified an existing framework (VN Framework by Woodsy Studio), but my problem is to figure out how to create a character selection menu, since scene datatables require a character to be entered from enums, not a variable. (I attach a screenshot)
Thanks if anyone replies!
