Source MongoDB: transfer _id fields as string not UUID

[GlauberF]

I'm migrating from mongoDB database to postgresql, I have several cases that a mongoDB object in postgresql will be more than a table.

In the process of migrating, I need to do some transformations and also be able to insert the value into a table, get the generated _id UUID and assign it to another table.

In the example in the image below, I try to demonstrate this.
I have an order object, in it I have customer and order details.
After migrating to postgresql, there will be two tables, 1 for the person and 1 for the order.
However, when migrating, it is necessary to create the record in the person table, retrieve the created _id and then create the record in the order table, also inserting the person's _id as a foreign key.

another challenge is to create a function that formats an old mongo _id into UUID, example:
Mongo id: 6248ae64b650c7fd1e041188
_id after parsing to UUID: 00000000-6248-ae64-b650-c7fd1e041188

I need to know how to include these transformations in the pipeline and how to insert in one table wait and insert in another.
