H5P grades for Moodlecloud

Hello dear members, 

I have a course on Moodlecloud and was able to add hp5 content as an External tool. However, in students grades report I can see these H5p activities and grades range from 0-100 but grades are always 0 regardless of the completion of the h5p activity.

Could you please advise is it possible to get and grades in Moodlecloud for h5p content in Grades section? Or it's not possible at all?

Thank you in advance.)
