• [nitpick] The method name 'Next' is somewhat generic; consider renaming it to 'ProceedToDatabaseConfiguration' or a similar descriptive name to clearly convey its purpose.

private async Task Next(MouseEventArgs args)

• [nitpick] Consider defining configuration key names as constants to reduce the risk of typos and to ensure consistency across the codebase.

public override string GetConfigurationByName(string name, string defaultValue = "")
