Can't include "Export As..." in an Action

I am not aware of any lack of functionality in actions with M1 Macs for Export > Save for Web (Legacy). Has this disappeared from the Export menu or just doesn't record correctly anymore? You could use Rosetta 2 if this made a difference... What about old actions, do they work?

Do scripts such as this one work?

/* This script exports a Save for Web JPEG to a user selected-folder, replacing file name word spaces with hyphens */

#target photoshop

if (app.documents.length !== 0) {
    // Remove extension and replace filename spaces with hyphens
    var docName = app.activeDocument.name.replace(/\.[^\.]+$/, '').replace(/ /g, '-');
    var docNameInput = prompt('Enter a filename (without extension):', docName);
    // Remove extension and replace filename spaces with hyphens
    var docNameOutput = docNameInput.replace(/\.[^\.]+$/, '').replace(/ /g, '-');
    var docPath = Folder.selectDialog('Select a folder to save the JPEG image to...');

    // File Path & Naming
    var saveFileJPEG = new File(docPath + '/' + docNameOutput + '.jpg');

    // Conditional overwrite check
    if (saveFileJPEG.exists) {
        // true = 'No' as default active button
        if (!confirm("File exists, overwrite: Yes or No?", true))
            // throw alert("Script cancelled!");
            throw null;
    }

    SaveForWeb(saveFileJPEG);

    // JPEG S4W Options
    function SaveForWeb(saveFileJPEG) {
        var sfwOptions = new ExportOptionsSaveForWeb();
        sfwOptions.format = SaveDocumentType.JPEG;
        sfwOptions.includeProfile = true;
        sfwOptions.interlaced = 0;
        sfwOptions.optimized = true;
        sfwOptions.quality = 70;
        app.activeDocument.exportDocument(saveFileJPEG, ExportType.SAVEFORWEB, sfwOptions);
    }

    // alert('JPEG saved!');

} else {
    alert('You must have a document open!');
}
