Determine which visual element was long-pressed in TouchEffect? - Xamarin Community Toolkit

I have an array of visual elements on a page, any of which can be long-pressed. In code, I can get a command to run when a button is long-pressed:

for (int i = 0; i < choiceButtons.Length; i++)
{
    TouchEffect.SetLongPressCommand(choiceButtons[i], new Command( async () =>
    {
        // Do stuff here, depending which button was long-pressed
    }));
    TouchEffect.SetLongPressCommandParameter(choiceButtons[i], choiceButtons[i].Text);
}

However, I need to be able to determine which visual element is the one that was long-pressed. Is there a way to do that?

(The visual elements are subclassed from Grid.)

[EDIT: Indexes corrected]

Here is the solution I found. Thanks to Jason and ColeX.

for (int i=0; i < choiceButtons.Length; i++)
{
    TouchEffect.SetLongPressCommand(choiceButtons[i], new Command(async () =>
    {
        // Here when a button is long-pressed
        object obj;
        for (int j=0; j < choiceButtons.Length; j++)
        {
            if (TouchEffect.GetState(choiceButtons [j] ) != TouchState.Pressed)
                continue;
            obj = TouchEffect.GetLongPressCommandParameter(choiceButtons[j]);
            if (obj != null)
            {
                MyButton btn = (MyButton)obj;  // This is the button that was long-pressed
                await HandleLongPressAsync (btn);   // Do stuff
                break;
            } 
    }));
    TouchEffect.SetLongPressCommandParameter(choiceButtons[i], choiceButtons[i]);
}
