How to code review a code without a creating a Pull Request

Hello,

@gitea dev team Thank you so much for Gitea, it is a fantastic software.

I would like to be able to initialize a code review in a Gitea repository.
However, the code review facilities are available only during an opened Pull Request.

How do you usually do a code review?
There is the option ¨Reference in a new issue¨ available, but it implies to create as many issue as comments one needs to make, and it is not easy to have a full outlook of the review.

Take care,

Facteur Pat
