I investigated and it looks like you may not have the required permissions to achieve this. Please ensure that you have the global admin rights and try again. If you still see this issue, let me know.
We have seen instances before when initial CycleCloud user created a user account for a second user. That second user then accessed Cyclecloud and found that they have too limited permissions to finish the CC configuration. In those cases, the first user needed to add additional permissions - global admin for the second user.
Also wanted to highlight that the free trial subscriptions usually only allow 4 vCPUs per family which isn't enough to get the full capabilities of cyclecloud.
