Rereading or relistening to what you said is one of the best ways to improve. Depending on your organization's setup, your simulation may stay available to review afterwards.
From your history
Open your session history, then the simulation you're interested in. There you'll find your debrief and, if recording is enabled in your organization, the conversation itself.
Recording and transcript
When your organization allows it, you can review the recording of the exchange and read its transcript, presented as a conversation. It's a chance to spot a word, a tone or a silence you didn't notice in the moment.
If nothing is recorded
To protect personal data, some organizations turn recording off. In that case, the conversation isn't kept: you keep your debrief, but not the video or the transcript. That's a choice made by your organization.
