Hi Lara,
Unfortunately, I do not know Arabic, so I cannot help you with this because I would not even know if something is correct or wrong. However, I found this potential solution in the official Unity forum. And this video on Youtube.
Also please feel free to ask our helpful community of students for advice over on our Discord chat server.
I hope this helped.
