There was a problem hiding this comment.
This is great!

❗ I have followed the Contributing to DVC checklist.
📖 If this PR requires documentation updates, I have created a separate PR (or issue, at least) in dvc.org and linked it here. If the CLI API is changed, I have updated tab completion scripts.
❌ I will check DeepSource, CodeClimate, and other sanity checks below. (We consider them recommendatory and don't expect everything to be addressed. Please fix things that actually improve code or fix bugs.)
Thank you for the contribution - we'll try to review it as soon as possible. 🙏
Related to #3811.
