How to translate toolbar buttons?

[Jarvil]

Hello,

I want to translate (to Finnish) all button hovers in course presentation toolbar but I don't know where to translate them to?

f.ex button called image. The text image doesn't exist in;

https://github.com/h5p/h5p-editor-course-presentation/blob/master/language/fi.json
or in
https://github.com/h5p/h5p-course-presentation/blob/master/language/fi.json

and it's already translated to h5p image -libary (which it could come from):
https://github.com/h5p/h5p-image/blob/master/language/fi.json

Any ideas?

This is currently not translatable since these buttons are using each library's name.
