Don't have the access to download UE

Good morning/afternoon

I’m working in a construction company and our company has a serious cyber security. With the support from Epic Game IT support, we successfully download the launcher.

However, there are other problems show up….In the Epic Game Launcher we downloaded, we don’t have the access to download the UE5 and Twinmotion. I’m new here and if I can’t use the software, I’m afraid that I cannot finish the work that my boss expected. I have attached the screenshot in this email. We cannot figure out how it happened. Can anyone help me? Any information is appreciated.

Thanks you so much!
