Object value reference from workflow task

Hello. I have a question about referencing an object value (Json format I think) from a workflow task.

For example, I get this object from the output of the following task

object returned:

{"CodeDesc":"Test Code ","User":"Test User","Email":"test@email.com"}

let say that this could be the first row in a given dataset, ok?

So, after that, I want to send an email to the "Email" address obtained from that task, for example using this:

The thing is, It's posible to make a reference to the "Email" directly from the "to" field in the sendEmail function?
In other words, It's ther a way that I can use something like {{object[2]}} in the "to" field of that task?

Thanks in advance.
