[BUG] MCQ/ DC buttons not displayed in chatbot

[matKlju]

Bug description:
Services that contain Multiple Choice Question (MCQ) or Dynamic Choices (DC) elements do not display the expected decision buttons in the chatbot.
When the service reaches the MCQ/ DC step, the chatbot only shows the question text, but the buttons are not rendered.

This makes the service unusable because the user cannot select an option to continue the flow.

Expected behavior:
When a service reaches a Multiple Choice Question (MCQ) node, the chatbot should display the configured buttons along with the question so the user can select an option and proceed in the service flow.

Screenshots:

Additional information:

The issue results in a broken service interaction, where only the first question appears but the required decision buttons are missing, preventing further progression in the flow.
