Let us paste a link into the contact's Slack profile into the field.

Use case: A big part of networking is meeting people in Slack communities. It's helpful to have a link to the profile/Slack DM where I do most of my conversing with the person.

A wrinkle is that sometimes, a contact I know is a mutual in multiple slack communities, so it might be needed to add multiple links to the contact's Slack profile in each Slack workspace.
