Fill in the Blanks

Hi,

I've been using the Quiz options in H5P in my Moodle (v3.8) portal to create quizzes. However, I've found that whenever students complete their quizzes, they would have to close that browser window, in order to get back to the previous tabbed page. 

Is there a way to put a URL link at the end of the quiz, so students can "just click" to move forward to another topic/quiz or wherever I'd want them to move forward to? Although this is available in the Interactive Video option, where I can set a pop up window at the end of a video that allows URLs to be linked.

I have tried to use the following code and am passing (to my knowledge) a complete $h5p_content array:

$H5PObj = H5PDrupal::getInstance();
$result = $H5PObj->insertContent($h5p_content, $contentMainId = NULL);

Am I missing something ? Do I need to call another function aside from insertContent()?

Does anyone know how to remove the blue band that now appears at the top of any new content that I make? For example here: https://h5p.test.schulcloud-thueringen.de/node/727542
