Database connection option is greyed out in database selection

If you're trying to set up a Database connection but the option appears greyed out in the "Select a database" screen, you need to create a new schema first. You can only create a connection within the same schema if it is of the same database type.

To resolve this issue:

1. Go back to the previous screen where you select your schema

2. Select "Create a New Schema" instead of using an existing one

3. Once you've created the new schema, the Database connection option should become available in the database selection screen

This requirement ensures that you have the proper schema configuration in place before establishing the database connection.
