@dianagociu, could this change potentially cause unintended updates? It seems the model might repeatedly update with the same configuration

@CarlaCostea, The previous condition was never true because responseAreaInputConfiguration.inputConfiguration.characters.disabled gets modified as soon as the toggle is switched. Consequently, I removed the condition to ensure the model updates properly. Repeated updates with the same configuration won't occur because the toggles ensure the method is triggered only when switched, resulting in a different value each time.
