Hi @Fatimah-Tariq possible for you to ask for one of following permissions from your admin looking after unity catalog.? granting permissions at higer level will pass thru to lower categories.

-- Grant WRITE on the catalog
GRANT WRITE ON CATALOG <catalog_name> TO `<user_or_group>`;

-- Or grant on a specific schema
GRANT WRITE ON SCHEMA <catalog_name>.<schema_name> TO `<user_or_group>`;

-- Or grant on a specific table
GRANT WRITE ON TABLE <catalog_name>.<schema_name>.<table_name> TO `<user_or_group>`;
