how to remove this wrap (mb-3):

class AuthForm(FlaskForm):
    hash = StringField("", validators=[Length(8, 256)], 
        render_kw={"class": "me-2"})

    submit = SubmitField("Auth", 
        render_kw={"class": "btn-outline-success"})

{{render_form(auth_form(), extra_classes="d-flex")}}

This div can't be removed, but you can set config BOOTSTRAP_FORM_GROUP_CLASSES to an empty string to make this an empty div.
