RMMV Force game message backround to be transparent

[Soulrender]

As title says, I've tried this code to make messages transparent for online version, but in all of my installed browsers:
Opera, Chrome, Brave messages display with default skin window.

(function(){
    
    'use strict';
    
    Game_Message.prototype.background = function() {
        this._background = 2; //transparent
        return this._background;
})();

Then I changed a little Game_Interpreter command directly in rpg_objects.js to following:

// Show Text
Game_Interpreter.prototype.command101 = function() {
    if (!$gameMessage.isBusy()) {
        $gameMessage.setFaceImage(this._params[0], this._params[1]);
        $gameMessage.setBackground(2);
        $gameMessage.setPositionType(this._params[3]);
        while (this.nextEventCode() === 401) {  // Text data
            this._index++;
            $gameMessage.add(this.currentCommand().parameters[0]);
        }
        switch (this.nextEventCode()) {
        case 102:  // Show Choices
            this._index++;
            this.setupChoices(this.currentCommand().parameters);
            break;
        case 103:  // Input Number
            this._index++;
            this.setupNumInput(this.currentCommand().parameters);
            break;
        case 104:  // Select Item
            this._index++;
            this.setupItemChoice(this.currentCommand().parameters);
            break;
        }
        this._index++;
        this.setWaitMode('message');
    }
    return false;
};

And still nothing, what am I missing with this?
(I'd like to mention I'm running tests on localhost and each change in code is followed with Apache restart, clearing all caches and tmp files).

Hi!

You can try do just that:

Window_Message.prototype.updateBackground = function() {
    this._background = 2
    this.setBackgroundType(this._background);
};

For better understanding, a transparent window, is only a window with their opacity set to 0:

Window_Base.prototype.setBackgroundType = function(type) {
    if (type === 0) {
        this.opacity = 255;
    } else {
        this.opacity = 0;
    }
    if (type === 1) {
        this.showBackgroundDimmer();
    } else {
        this.hideBackgroundDimmer();
    }
};

Ohh darn... I Forgot about Window_Base...

That solved problem, Thank you @Eliaquim .
