Thanks for your question! Currently it's only possible to embed a Roadmap View of your plan into Confluence - unfortunately embedding a dependency report is not supported.
Please feel free to use the "Give Feedback" button at the top right corner of your plan to submit a feature request if this would be beneficial for you. Unfortunately I can't give any guarantees that it will be worked on, but that's the best route to make the team aware of your use case.
