Quick Complete Text Help View Example doesn't display

Using Joomla 4.1.2 and PHP 8.0.13 with Simple Quiz 1.9.970. 
In admin for a quiz in the Quiz Texts tab, when I click on View Example for Complete Text Help, nothing happens.
There are no errors on the JavaScript console.
If you could point me to an example, that would be great.

I have been working with Simple Quiz on a Joomla 4 test site. I am migrating to the live site, which is still on Joomla 3.10. This works fine on Joomla 3.10, so I have the info I need.

Hi again John. Thank you for your post.
You are right. It seems that this is an incompatibility with the version of bootstrap used by Joomla 4.
I will fix it and let you know.

After looking into this, it seems that while our help modals did work at an earlier version of Joomla 4, they have now stopped.
I just fixed them and will release the fixed version later today.

Thank you for letting us know!
