How can one match this pattern inside CtForEach and CtLambda

Given snippet that looks like `list.forEach(item -> assertTrue(setBasedOnList.contains(item)));`

I would like to transform it to:

`list.forEach(item -> {});`,

such that I could insert multiple CtStatement inside the CtBlock.

Ps. I also encountered weird behavior where snippet.getElement(TypeFil... (CtForEach.class)) outputs null.

Thank you!
