Image Multiple Hotspot Question in Dutch: call for help!

Hi everyone!

I created a Multiple Hotspot Question exercise in Moodle, however, the language is in English. I need it in Dutch. The only thing that needs translating is the word 'of' (in '1 of 4 hotspots') to 'van de'. I tried to contribute to this content type via GitHub with the instructions available. There does not seem to be a language file (https://github.com/h5p/h5p-image-multiple-hotspot-question) for me to edit/contribute to, and I by no means have the ability to make one myself (I really barely understand any of this). This is a call for help: is there anyone who can help me make sure that I can use the content type 'Find Multiple Hotspots' in Dutch, or at least that one word? You would be a lifesaver!

Thanks in advance!
