Can't see Grafana images in Slack

Question

I set up a Slack notification channel in Grafana using a webhook as URL. When I click "Send Test" I see this notification in my Slack channel:

However ordinary notifications are shown without images. I read Grafana's docs, but apparently I haven't understood it.

If you want to include screenshots of the firing alerts in the slack messages you have to configure either the external image destination in Grafana, or a bot integration via Slack Apps. Follow Slack’s guide to set up a bot integration and use the token provided https://api.slack.com/bot-users, which starts with “xoxb”.

Can someone guide me through it? I created a new bot and generated a token for it (starts with xoxb as requested) but how do I keep going from there?
