python - using flask_wtf.csrf without wtf_forms

Question

I have a simple flask web app and I want to use flask_wtf csrf protection but whenever I try to run to submit the form I get an error saying I am missing the CSRF token.

Is it even possible to use csrf without wtf forms? and if so what am I doing wrong?

my code:

app = Flask(__name__)
csrf = CSRFProtect(app)

@app.route("/reserve", methods=["GET", "POST"])
def reserve():
   if request.method == "GET" :
       return render_template("reserve.html", **context)


<form id="Reserve" action="/reserve" method="post">
   <!-- csrf protection -->
   <input type="hidden" name="csrf_token" value="{{ csrf_token() }}"/>
   <input type="text" placeholder="Name">
   <button type="submit">
        Submit
   </button>
</form>
