As a tenant’s administrator, if you install Slack you configure the following properties to allow Challo to access your organization’s Slack account:
|Access token||Provide a legacy Slack API token for your workspace.
See: Slack—Legacy tokens
If you cannot create a legacy token, you cannot associate your organization’s Slack account with Challo, instead your members have to use add their own accounts.
If you do no provide an access token and allow member accounts, members of your organization can add their own Slack accounts using the Add menu.
