You can check these requirements to create and manage catalogs:

To get started with Unity Catalog in Azure Databricks, the first Azure Databricks account admin must be an Azure Active Directory (Azure AD) Global Administrator.

When you log in as a Global Administrator into the Azure Databricks account console for the first time, they are automatically assigned the account admin role. After this initial setup, you no longer need the Azure AD Global Administrator role to manage Azure Databricks.

The first account admin can then assign additional account admins from the Azure AD tenant. These additional account admins don’t need any specific roles in Azure AD to perform their duties or to assign other account admins.

Log in to the Azure Databricks account console using a Global Administrator account. Once logged in, you can ADD Users & groups.
