Console FireEdge VNC

We are trying OpenNebula and there is an error that I do not understand.
I created an OpenNebula instance with the OVA on VMWare, then import some vm, create some users.

When opening the console, if I am with the oneadmin user, I see in the logs that it opens the console to me via FireEdge and it works fine.
On the other hand, after creating a user and assigning VMs, if I open the console with the user, it tries to connect with VNC, but I don’t have VNC on the esxi so the connection is refused.

How can I get my regular users to access the console through FireEdge?

Thanks for your help
