Can I have access to the Case Management Model and Notation (CMMN) in my workspace?
CMMN is an additional module to the Signavio Enterprise Edition. It can be activated on request by the Signavio Support Team (firstname.lastname@example.org).
You can find more information about the CMMN here: https://docs.signavio.com/userguide/editor/en/modeling_and_notations/cmmn/index.html
