Rasa X - Defining roles and groups in domain.yml

[Deprecated] Rasa X Community Edition
1

From last few versions, Rasa X seem supporting the definition of roles and groups in NLU data, but when I define it in domain.yml under entities, show no error but the roles and groups will get wiped off after saved. Is that Rasa X is still not supporting roles and groups yet?
