How to commit to github so that the activity is reflected in the panel?

Question

GitHub

Good evening.
The Contributions panel (the one with squares) doesn't show my commits other than the ones I suggested in the pull request. I guess it's because I don't commit to master directly (and github says only commits to master count). My development cycle looks like this:
- create a new branch
- commit changes until the branch reaches the release stage
- create a release from this branch
- merge (--no-ff) and commit to master
In theory, this commit should be taken into account, and since all commits from the branch are transferred to the history of the master, they should also be taken into account, but no. How to be? Throw on this feature, or push all the changes without releases, according to the methodology "hoo*k-hoo*k and into production"? Perhaps I'm doing something wrong, or is this functionality simply unusable and ignored by reputable developers (it's not for nothing that there were solutions that allow you to draw different pictures from squares there)?
Thanks in advance.

Answer 1

So merge without (--no-ff)
With (--no-ff), commits are not migrated.

Recently faced the same problem. Littleguga's answer seems to be correct, but I don't know.
