New Branch from Intellij not visible in Gitea

I create a new Branch in Intellij and push it to git/gitea. But the branch is invisible in Webinterface until i use “Administration” → “synchronize branches from gitdata” in webinterface - that works, but have to do it manualy.

As a workaround i tried cron task with following command … but does not update the repo database.
sudo -u git gitea doctor check --config /etc/gitea/app.ini --work-path /var/lib/gitea
Any advices?

I use gitea 1.23.7 on a raspberry pi 5, i work under Admin user rights, git version 2.39.5
