[Paul-Bob]

Context

Passing parent record as argument as explained in detail here https://github.com/avo-hq/avo/discussions/3159#discussioncomment-10405595

Demo commit: https://github.com/avo-hq/avo/commit/b55d4e49e7e667ceb59e561222f12e5fc1eb117f

Approach

• Document the workaround OR
• Implement a way to access the parent record on actions def fields and def handle methods.
