Material Management Roles and Visibility Issues in 3DEXPERIENCE Public Cloud

I am currently using 3DEXPERIENCE Public Cloud, 3DEXPERIENCE SOLIDWORKS, Cloud SOLIDWORKS, XEN, and MFN.

I'm trying to use the "Make from" and "Material" functions in XEN. While I can see the Material list in xDesign's Library, it's not visible in XEN.

Additionally, I'd like to know which role allows for creating and modifying materials in the Cloud environment. The XSR role you recommended in ENOVIA MAX only supports on-premise installations.

Could you please provide guidance on accessing the material library in XEN and explain the necessary roles for managing materials in the 3DEXPERIENCE Cloud environment?
