How to load .txt file in Android

Hi, I'm making a Word-based game and I'm loading all the words through smalls .txt files (each files represents a Word Category. e.g: Animals, Food, etc.).

Currently I load them like this:

 using System.Collections.Generic;
 using System.IO;
 using UnityEngine;
 
 public static class WordsLoader
 {
     public static List<string> words = new List<string>();
 
     public static void LoadWords()
     {
         DirectoryInfo path = new DirectoryInfo(Application.streamingAssetsPath);
         FileInfo[] files = path.GetFiles("*.txt");
         foreach (FileInfo file in files)
         {            
             string filePath = file.FullName;
             string[] lines = File.ReadAllLines(filePath);
             for (int i = 0; i < lines.Length; i++)
             {
                 lines[i] = lines[i].ToUpper();
             }
             words.AddRange(lines);
         }
     }
 }

And it works perfectly on the Editor, but while testing the .apk on my phone, it doesn't. I soon found out that Android doesn't load files like these but I couldn't get anything that I searched to work.

This is my first time making a Word game, a mobile one and using files, so I could have not done this the most optimal way, but it's just for learning.

Note: The foreach part is VERY important since I store each word per line, which is a very nice and simple way of getting them into the List, so I would like to keep that (well basically the FileInfo class that gives me that).

Thanks!
