Trigger plugin function when clicking on an object in prototype mode

Hi,

is this possible?

• User clicks on object (e.g., a rectangle) in prototype mode
• This triggers a function call in my plugin

Currently, I can associate various actions with an object, e.g.,  “navigate to”, “set variable”, “open URL”, but I couldn’t use it to trigger a function in the plugin.

I tried observing variables, but variable changes triggered in prototype mode don’t seem to reflect in the plugin.

Maybe there is a deep link into the plugin that I can trigger with “open URL”?

Any suggestions welcome. Thanks in advance.

Markus
