Cloud Platform limits the actions you take in the user interface with the teams, roles, and permissions system. In some cases, if you do not have permission to take an action, the interface control is present, but disabled. In other cases (for example, the Subscriptions page if you are not the Owner or Administrator of the subscription), the control or page is not displayed.
If there is an action you want to take, but cannot check your roles and permissions in the Manage page of the Cloud Platform user interface. On that page, you can also find the names of the Owner or Administrator of each organization of which you are a member, and the names of all the teams and the team leads. Depending on your goal, you can contact the Owner, Administrator, or Team lead and request the role you need.
