Add uBPMN to Camunda Modeler

Dear people,

i need to add a extension to the Camunda Modeler so it can use uBPMN (its like 10 more events).

uBPMN (ubiquitous BPMN) - more information in this file UBPMN.pdf (3.8 MB)

I’ve already read some documentation on github but I don’t know how and where to put the XML Code of uBPMN which is in the file above.

Hope somebody can help me.

To specify my need:

I have to add 5 new tasks 10 new events and 1 new type of object to camunda modeler.
For example here are some tasks and the smart object.
