How to only list TODOs in files changed in the current branch?

[carlos-algms]

Scenario:
I create a new branch.
I'll add TODOs as I edit files
These TODOs must be fixed before merging the PR.
They are also valuable in code reviews, as other team members can catch leftovers.
The project is huge, so there are TODOs from other people and teams that aren't relevant to this PR.

How could I list only the TODOs on files changed in this current branch compared to main branch?
