Hyperlink to Slack

[mckoss]

It would be nice to incorporate deep links in these docs to slack users and channels:

https://api.slack.com/reference/deep-linking

This works:

Channels:
https://slack.com/app_redirect?channel=track-frontend

I can't get this to work:
Users:
slack://user?team={TEAM_ID}&id={USER_ID}

TEAM_ID: T01NE9BR213
xylzul id D01PHF49PG8

so:

slack://user?team=T01NE9BR213&id=D01PHF49PG8

https://slack.com/app_redirect?user=xyzul
