Hi, I need more information about member permission. I have private project that only shared via link invite. It works fine but I have report that "observer" can't see/change project version and getting permission error when opening BoM. Also can't clone the project. My question is what permission should I give to have that feature (clone, view version) but not able to to edit the file (schematic/board)? The explanation [here](https://docs.easyeda.com/en/Introduction/Project-Member/index.html) is still unclear. Thanks.
