Is your feature request related to a problem? Please describe.
GitHub is trialing a new experience for navigating changes in a pull request. The classic and new experiences are accessible via slightly different URL paths:

• Classic experience: https://github.com/[organization]/[repository]/pull/[pr-id]/files
• New experience: https://github.com/[organization]/[repository]/pull/[pr-id]/changes

When using the the classic experience in GitHub, the Codecov Chrome extension injects coverage information at the top of the page. In the new experience, I do not see any coverage information.

Describe the solution you'd like
Replicate the classic experience behavior for the new experience.

Describe alternatives you've considered
No alternatives considered.
