Is it possible to show pull request differences between two branches on Visual Studio Code?

[ugultopu]

Using GitLens, native VSCode or some other solution, is it possible to show the changes of a pull request directly on VSCode? AFAICT, a pull request difference is a triple-dot difference between the default branch and the feature branch. I know that GitLens has a feature for comparing references, but as far as I can tell, this feature uses the two-dot difference. This doesn't help me, hence I need a solution to show the actual differences between two branches, starting from merge-base.
