Need to change feedback field max text length for Drag n Drop content to 500

Hi All,

I am using the H5P plugin for adding interactive quizzes on our course website using Drag n Drop interactive content.

Under settings (under WordPress dashboard) in the H5P plugin, under ‘Tips and Feedback’ section, the max length for feedback input text field is 255. I need to change it to 500.

Can someone help me to the files where this change needs to be made? I am not able to find the HTML or JS file where this change can be made. Attaching the screenshot with the field for which the max length has to be changed.

The page I need help with:
