Sending Slack invites

When new member signs up how with zapier can I send an invite to private slack for members only? In zapier screenshot it seems I can only invite to a channel?

Hey David :wave:

Currently, Zapier does not have an action that will add new users to Slack. I understand this is frustrating. I myself want this feature as well! To get around this I suggest sending a Slack invite link through email using Zapier when a new member is added. :smiley:
