Currently, there is no way to specify which labels Crowdin uses when creating a PR through the GitHub integration. I think it would be nice to add this option to the crowdin.yml file. Somthing similar to what Dependabot offers would be wonderful (see Configuration options for the dependabot.yml file - GitHub Docs).
@rickstaa currently, the native GitHub integration do not support the PR labels but it’s already available in the Crowdin GitHub Action by using the pull_request_labels option
