Export file in cordova app not working

My export (Print) file is not downloading any file on my Cordova-generated android app. But everything works fine on the spa from both mobile and desktop browsers.

On the android app, I can see the action red line fully loading on top but nothing appears as downloaded. Please assist.

I have added the following into my config.xml and AndroidManifest.xml but still can’t see any file.

<preference name="AndroidPersistentFileLocation" value="Download" /> 
<preference name="AndroidExtraFilesystems" value="files,files-external,documents,download,root" />
    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />

Try following the instructions here [Solved] [V1] Download a file in Cordova app | Quasar Framework Community (quasar-framework.org) and see if it helps. Below you’ll find the file you have to modify to apply the instructions from the quasar forum.

The export code is located on line 100 of project root/frontend/src/composables/app.js, but the main code is located on line 119:

	function exportPageRecords (pageExportFormats, currentPageUrl, pageName) {
		let actions = [];
		pageExportFormats.forEach(format => {

		let message = $t('export');
			grid: false,
		}).onOk(action => {
			let selectedExport = menus.exportFormats[action.id];
			let queryParam = {
				export: action.id
			let exportUrl = utils.setApiPath(currentPageUrl, queryParam);
			let fileName = `${utils.dateNow()}-${pageName}.${selectedExport.ext}`;
			ApiService.download(exportUrl).then((response) => {
				const url = window.URL.createObjectURL(new Blob([response.data]));
				const link = document.createElement('a');
				link.href = url;
				link.setAttribute('download', fileName);
			(error) => {
				alert("Unable to download file")
		}).onCancel(() => {
			// console.log('Dismissed')
		}).onDismiss(() => {
			// console.log('I am triggered on both OK and Cancel')
