I want to change my list

Hi, I’m brand new to thunkable and I’d like to create an action or truth type application for my friends. My first problem is that I want to be able to mark the names of players in a text entry that I already have and therefore add this to a list, but I don’t understand how to do this.

Hello @maxenceroger3.5r6bi4 Welcome to the community
Could you please share more information about the list of names?
Will it always be the same names?
Do you need to build a function to add names?
