[Flask] render_template_string doesn't render

            I have the following:
def get(self):
    return render_template_string('<h1>PLEASE CLOSE THIS WINDOW</h1>')

When the following is called what is displayed in the browser is :

It doesn't get rendered.  I have tried various option as seen on the web, such as:

return render_template_string('''<!doctype html>
        <link rel="stylesheet" href="css url"/>
        <p>Hello, World!</p>

It just displays the html, it doesn't render it.  I have also tried render_template('pleaseclose.html'), it also just displays the html in the file and doesn't render it

               The way the get(self) is called is by a callback from an OAuth2 request.

Any thoughts ?

Thank you
