Anyone found a good way to run performance reviews inside Teams?

Our company just switched to doing everything in Teams and the one thing that still lives outside is performance reviews. We use a separate web app that nobody logs into until the last minute and managers hate it. Is there anything that actually handles the full review cycle with self assessments, manager ratings, maybe even 360 feedback? Our IT team said they'd prefer something that uses our existing M365 directory so we dont have to manage another user list.
