Graylog 4.0 can't add Slack notification

Hi,

I’m trying to use the new Slack notification official support, but I can’t find it in the notification type, here is the screenshot:

I also attached the logs from a fresh restart of Graylog. I have no additional plugins installed. This is an upgraded installation.

thanks, Diego

Please close it as I noticed that I haven’t the integrations plugin installed.

Thanks
