How to download file and redirect user to another webpage using flask?

so I have been trying to make a website and I am encountering an issue here is my code

@app.route("/Download")
def download_final():
    lol = os.environ.get("hell")
    path = (f"Downloads/{lol}")
    return send_file(path, as_attachment=True)

@app.route('/remove')
def remove():
    os.remove("key.key")
    foo = os.environ.get("hell")
    os.remove(f"Downloads/{foo}")
    return render_template("remove.html") 

• want to download file and then redirect user to another webpage where the user can agree and remove the file from server.

So I found this return send_from_directory() and redirect(url_for()) from here by using this method I am able to redirect but file is not being downloaded so then I noticed that when I redirect it remove those files so just to try this again I switched the path to homepage and started my website again I as getting the same issue redirect is working but file is not being downloaded
