is there no type for BoundaryEvents?

Hi, I’m trying to simulate some processes with bpmn-js. Regarding BoundaryEvents, is there really no type like “Message_Boundary_Event” in the elementRegistry or in the bpmn file?

https://forum.bpmn.io/ is the appropritate forum for bpmn-js-related questions.

Cheers,
Thorben

Thank you!!
