AEM Forms - Using AssemblerService - how to configure insertionPoint in LiveCycle designer and use it via DDX

Env. AEM Form 6.5 SP-12 On Prem, Document Manager version [1].

Question - Using AssemblerService - how to configure insertionPoint in LiveCycle designer and use it via DDX

Scenario - We are trying to configure insertionPoint (DDX [2]) as explained here -

https://help.adobe.com/en_US/livecycle/11.0/dynamic_assembly_guidelines.pdf but it does not work.

Question is:

• Does AssemblerService (as mentioned above in Env.) still supports insertionPoint or not?
• Is there any alternate feature available or not OOTB in AEM Forms?
