Upload excel file to google drive in Laravel 7

Storage::disk('google')->put('test.txt', 'Hello World');

And

Storage::disk('google')->put('test.json', json_encode(Inventory::all()));

above two types of file uploading to google drive by using google-api-php-client and nao-pon/flysystem-google-drive packages is working well in my laravel application.

    $filename = 'inventory'.date('dmY').'.xlsx';
    Excel::store(new InventoriesExport, $filename);
    $path = storage_path($filename);

I have saved excel file with data from database in local (app/public/storage). can anyone help me to upload/ save this excel file to google drive?
