How do I export all open files into PNGs and have every window close in the end?

Last year, I had help with making an Illustrator script that hides the text layer of all open files and saves every one, but I am wondering how to add code that exports all the files into PNGs (to the size of the artboard) and close all the open windows in the end.

I have been doing this just by using a Batch PNG export action in Illustrator and then manually closing everything, but I figured it would be more efficient to have it all included in one script. Thank you anyone in advance for helping out!

for(var i=0;i<app.documents.length;i++)
{
        var oDoc=app.documents[i];
        for(var j=0;j<oDoc.layers.length; j++)
            {
                if(oDoc.layers[j].name=="text")
                {
                    oDoc.layers[j].visible=false;
                 }
                 if(oDoc.layers[j].name=="text2")
                {
                    oDoc.layers[j].visible=false;
                 }
           }

}

#target illustrator

function test(){

 

  for(var i=0; i<app.documents.length; i++){

    app.documents[i].activate();

    app.activeDocument.save();

  };

 

};

test();

I have been looking for a solution but I haven't seen anything.

I merged the script that coolshrimp suggested with another script that applied the script to an entire directory and it worked smoothly! This is the script I merged it with -> Running a script on all .ai files in a directory

    #target illustrator



// Function to unlock all locked layers in the document
function unlockAllLayers(doc) {
    function unlockLayers(layer) {
        layer.locked = false;
        for (var i = 0; i < layer.layers.length; i++) {
            unlockLayers(layer.layers[i]);
        }
    }

    for (var j = 0; j < doc.layers.length; j++) {
        unlockLayers(doc.layers[j]);
    }
}

// Function to remove all layers containing text items
function removeTextLayers(doc) {
    for (var j = doc.layers.length - 1; j >= 0; j--) {
        var layer = doc.layers[j];
        var textItems = layer.textFrames;
        
        if (textItems.length > 0) {
            layer.remove();
        }
    }
}

// Function to export the active document as a PNG with the same name
function exportPNG(doc) {
    var pngOptions = new ExportOptionsPNG24();
    pngOptions.artBoardClipping = true;
    pngOptions.antiAliasing = true;
    pngOptions.transparency = true;

    var file = new File(doc.path + "/" + doc.name.replace(/\.[^\.]*$/, '') + ".png");
    doc.exportFile(file, ExportType.PNG24, pngOptions);
}

function main() {

    var folder = Folder.selectDialog('Please, select the folder');
    if (!(folder instanceof Folder)) return;

    var files = folder.getFiles('*.ai');
    if (files.length == 0) {
        alert('Folder doesn\'t content AI files');
        return;
    }

    var i = files.length;
    while (i--) {
        var doc = app.open(files[i]);
        unlockAllLayers(doc); // Add this line to unlock all layers
        removeTextLayers(doc);
        exportPNG(doc);
        doc.close(SaveOptions.DONOTSAVECHANGES);
    }

    alert(files.length + ' files were processed');
}

main();

I also made an alternate version using the script I was given last year that hides text layers with specific layer names. This replaces the part that starts with "// Function to remove all layers containing text items"

// Function to remove all layers containing text items
function removeTextLayers(doc) {
    for (var j = doc.layers.length - 1; j >= 0; j--) {
        var layer = doc.layers[j];
        var textItems = layer.textFrames;
        
            {
                if(doc.layers[j].name=="text1")
                {
                    doc.layers[j].visible=false;
                 }
                 if(doc.layers[j].name=="text2")
                {
                    doc.layers[j].visible=false;
                 }
                 if(doc.layers[j].name=="text3")
                {
                    doc.layers[j].visible=false;
                 }
           }
    }
}
