Create a collaborative space

Hi everyone,

I try to use 3dexperience engineer since yesterday. When I want to launch for example assembly design, this message appears... I saw that we've to create a collaborative space, how can we do that? I found a video which explain how do that, I think, but when I follow the instructions, I can't create beacause it doesn't like as in the video... Is anyone can help me please? Thanks
