Hey! I totally get what you're experiencing, as I ran into the same issue. It looks like Databricks has updated their UI a bit. Previously, the "Create Catalog" option was under the settings wheel icon when accessing the catalog in Databricks workspaces. Now, it seems they've moved it to the "Add Data" section.

Just a heads up, make sure you have the appropriate privileges—either being a metastore admin or having the CREATE CATALOG permission—otherwise, you won’t see the option.
