The sprint review is a specific timebox at the end of the sprint to review the deliverable of that sprint. This is a conversation about the quality of that deliverable. Project stakeholders should be invited to this meeting to offer feedback. This allows for teams to know if they are going in the right direction or if they need to adapt/make changes.
Here is a template to guide you through this discussion. You may also (or) take notes on the review column of your sprint backlog. This is also another template that includes both review and retro ceremonies agenda questions.
