Passing objects as variable in Flows

My question:
I’m trying to create an object out of multiple variables (using Record), and then pass that one down into a request body key. The thing is that by doing that, the object is stringified and the api request fails.
How can I achieve this?

Screenshots:

You can tell that, while the output and variable are JSONs, the body looks as follows:

I’ve already tried:

  1. the example above
  2. Using the output directly into the request instead of using a variable.

I could get around this by being able to encrypt/decrypt an object using the same methods as I do in pre-request scripts (using this method), but nothing like that seems to exist in Flows for now

Does anyone have any clue on how to achieve this?

Thanks for any help!
