Use element templates with a custom widgets

Hi!
I use element templates to add custom properties. This was done straight forward. Great! Now I like to add a specific UI-widget to the properties panel to edit these custom properties in a convenient way. I already coded an EntryFactory. How do i register my custom EntryFactory for the type of the custom property?

Greetings
Stefan

Are you trying to add this to Camunda Modeler? If so, I believe the only way you can do this is to modify the code itself.
