Blueprint condition selector as trigger?

Configuration
1

I would like to use a condition selector instead of a boolean in a blueprint and use it as a trigger. Is that possible?

{{ true is in mycondition }}

{{ mycondition }}

I have tried different variants (variables set in trigger_variables, of course).

This is roughly how I integrated the condition selector in the blueprint.

conditions:
  name: Additional conditions
  description: Add conditions to prevent changes in position
  default: []
  selector:
    condition: {}

Is there any way to trigger it?
