How to add required asterisk to Quiz Label and style it?

[ad_1]

I am trying to add an asterisk in html format like this:
*

to the Quiz label on a contact form. No matter what I try, the styled asterisk gets removed once the page completely loads.

Here’s an example of a script I have applied to the page:
jQuery(document).ready(function($){$(“.wpcf7-quiz-label”).append(“*”);});

I think there is something special about the quiz field / label that is preventing me from doing this. How can I work around this?

The page I need help with: [log in to see the link]
