fix(exporters): auth token

[VTrngNghia]

What does this PR do?

Fixes an issue I found myself while trying to access a private HuggingFace repository: the framework doesn't pass auth token down to necessary functions.

Who can review?

Any one. It's a very simple fix.

Thanks a lot @VTrngNghia, by coincidence this appears to have been fixed through #1947
