Do I still have to do a self-assessment if my capital gains are fully offset by losses in previous years?

• 2022/2023 - losses
• 2023/2024 - gains
• 2024/2025 - gains above allowance (at around £4.5k)

The loses > all gains combined

Do I still need to file a self-assessment?

If not, should I still file one anyway at some point to make sure HMRC is aware of my losses?
