How to transform a copy of the original table with Power BI?

Question

I'm totally new to Power BI. I want to transform a table but a copy of my original table, not the original table.

My Power BI Desktop is in French, so please excuse me if I don't provide the correct English wording.

First, I know how to make a copy of my original table. I go to "Modelization" -> "New table" and I type "MyDataCopy = MyData".

Then I go to "Welcome" ("Accueil" in French, perhaps the translation is "Home" rather than "Welcome"), and I select "Transform data". Here I do my transformations. But that's always the original table MyData which appears, and even if I rename it before doing the transformations, the original table MyData is replaced with the transformed table when I click "Close and apply", with the new name.

How to do the transformations to "MyDataCopy" instead?

I'm sure it's pretty easy, sorry for the newbie question.

Ah, I've found!

In the Query editor, which opens when I click "Transform data", I can right-click on "MyData" and duplicate it. Then I perform the transformations on the duplicated data.
