Flow notification to specific person

Hello,
I use nextcloud in the latest version.
I have now installed the app flow so that predefined processes happen automatically.
Here’s what I want to do, when I upload a photo, I want certain people to get a notification via nextcloud talk that something new has been uploaded to a certain folder. Unfortunately, my settings are not working. Can someone take a look at this, thanks.
