New Database

how do I make a new database from CloudKit dashboard?

When you configure your app to use CloudKit, 3 databases are created for you automatically: public, private, and shared. You don't create them yourself.

You'll need to read the documentation for a full understanding, but a good place to start is https://developer.apple.com/documentation/cloudkit/designing_and_creating_a_cloudkit_database.
