In a community post it was brought up that it would be nice to be able to resolve a comment in the VS code extension: https://community.atlassian.com/forums/Bitbucket-questions/Resolve-comments-in-VS-Code-PR-integration/qaq-p/2995769

The Codebase for that extension lives here: https://github.com/atlassian/atlascode/tree/main

And there is a public API for resolving a comment: https://developer.atlassian.com/cloud/bitbucket/rest/api-group-pullrequests/#api-repositories-workspace-repo-slug-pullrequests-pull-request-id-comments-comment-id-resolve-post
