I am wondering how could I make the following commuting diagram

enter image description here

using only tikzcd. I have constructed the diagram without the circular arrows; you may find the code below. However, I don't know how to insert these arrows in the diagram. I am also interested in reproducing these kind of diagrams in the future, so I would really appreciate answers which could allow me to insert this type of node into other digrams.

Thanks in advance for your answers.

  • Not quite, for the accepted answer relies in manipulating the arrows and making them shorter.

It can be done with a phantom arrow, like this:
