After installing the app, approve the permissions.
1. Click the settings in the top menu

Then you should reach the settings page. Click "Integrations":

Click the "Connect slack" button

Authorize the permissions:

Select the channel (Notice if it's a private channel, first go to that channel and send a message tagging "@OpenPolicy" and hit "Add them to channel" to be able to see it in this list):


Once you have selected a channel, you are all set. You will start receiving important policy updates as they arrive to that channel.
