I run slack as a snap application. To recognize and adjust slack notifications I changed .desktop properties. According this link, I added X-GNOME-UsesNotifications=true in /var/lib/snapd/desktop/applications/slack_slack.desktop.
Now, in notifications settings I see the slack application and I can change the bevaviour for slack. But the slack-notifications are still received with "others" instead "slack".
How can I change? Is there a possibility?
