Load CSV file from local drive into DataTable for Cesium

Hello, I have followed the tutorial from Cesium concerning a flight tracker (Build a Flight Tracker with Cesium for Unreal – Cesium) and they import the CSV there as a DataTable . I was wondering: how can I load any CSV file from my local Windows drive into the game as a DataTable , at runtime (so when playing the game). I would like to go to the result where the player imports a CSV from his/her local drive into the game at the start, and then the flight starts. Does someone has experience with this?

There are plugins that can do it.
Or you can do it in c++,. code is simple and standard stuff. Maybe there are ready snippets to do it.
And i think (but i am not sure) that unreal c++ has already CSV code, all you need to do it declare blueprintable functions for it and compile.

I read about the Victory Plugin that could do it, but how is a mystery. Concerning C++: I’m happy to use that, but I have not found any snippits and/or tutorials on how to do this properly.
