Get Widget instance from game instance class

This has been bothering me for weeks! I have a PlayerList Widget that is created on begin play that shows player names as they are added to the game. In my “MyGameInstance” c++ class, I have an “IsJoined” function which I want to use to add players to scrollbox of PlayerList Widget as players join the game. However, I’m having problems accessing the instance of “PlayerList” Widget that currently exists in the game.

I trying to do something like:

void UMyGameInstance::IsJoined(Person P){

//Get instance of PlayerList widget and add new player to scrollbox of PlayerList widget


Please help :frowning:
