Session Replay Setup in GTM: Concerns About Template Update and Data Loss

Hey , I was trying to enable session replay for my account in GTM using the Mixpanel template, but the "init" and "record session" tag types are not showing up. I think the issue might be with the template, and we may need to update it. However, I just want to confirm that updating the template will not cause any data loss for the existing tag-based events. Could you provide some information regarding this?
