unity – Retrieving an array of images from Firebase Storage

As title says I’m trying to get all images on firebase storage and save them to an array which later on i will be using to load them into the scene. i can manage downloading on image so far but I’m unsure of how to make them into an array.

This is the code I’m using now to download one image by name and assigning it into a texture variable

        storage = FirebaseStorage.DefaultInstance;
        storageRef = storage.GetReferenceFromUrl(_url);

        storageRef.Child(_resourceName).GetBytesAsync(1024* 1024).ContinueWithOnMainThread(task =>
            if (task.IsCompleted)
                Texture2D texture = new Texture2D(1, 1);
                byte() fileContent = task.Result;

                selectedText = texture;
            if (task.IsFaulted)
                Debug.Log("faulted DOWNLOAD");


now through that i want to replace my current function which loads all images through the inspector.

 if (LevelSystemManager.Instance.CurrentLevel < source.Length)
            selectedText = source(LevelSystemManager.Instance.CurrentLevel);

Source being the array i use from the inspector to load those images into the game scene which then are selected into the selectedTex Texture2D and loaded based on the level, so 0 element in array == level0 , 1 == level 1 etc. etc.

So i was wondering if i have a couple of folders inside firebase with 10 to 20 images each how can i make that source array pull from that folder? And as a result remove the need to have them in the game and of course not setting them through the inspector.
