Clarification on Dovetail User Notifications for SSO Groups

I’m looking for clarification on how Dovetail handles user notifications when adding people to an SSO group. As I understand it, users aren’t actually created in Dovetail until they log in for the first time with their SSO credentials—meaning they also wouldn’t receive any notification emails from Dovetail until after the login for the first time. Can you confirm if this is correct? The reason I’m asking is that we’d like to preemptively add all colleagues from a specific business area to our Dovetail SSO group, but we don’t want to spam colleagues with an email announcing their access. Ideally, they would only realize they have access when they encounter a shared Dovetail link in Jira or Confluence and log in for the first time. Would appreciate any insights—thanks
