High cyclomatic and cognitive complexity in initButtons method

[Sonath21]

The initButtons method in the project has extremely high cyclomatic complexity (52.0) and cognitive complexity (156.0). These values significantly exceed the acceptable limits, indicating that the method is difficult to understand, test, and maintain. In order to manage it, you could refactor the initButtons method by breaking it down into smaller, more manageable sub-methods to reduce complexity and improve code maintainability.
