Docs feedback: Note incorrect on Slack integration page

Problem to solve

In this section: https://docs.gitlab.com/ee/user/project/integrations/slack.html#gitlab-configuration Say: Note: Usernames and private channels are not supported. To send direct messages, use the Member ID found under user’s Slack profile.

But i was able to do it with a private channel.

Further details

I just reference in the integration webhook of Slack the private channel and it works.

Proposal

Remove that note, please.
