Image editing in MuseScore 4

So when creating scores, I usually like to add a picture as a cover to make the score look more 'put together' and it adds a nice effect. However, I recently tried this in MuseScore 4 and I was able to load the image just fine (png), but was unable to edit it. Over in the properties panel, I was able to minimally edit position, but there is no choice for changing size or being able to change it with the handles that frames and text boxes have. Am I missing something? This is just a minor problem, so if it's just a bug or something that is not in MuseScore 4, I'll just work around it. I have not found anything about this in the handbook for MS4.
