[R] How to apply for a reviewer role at NeurIPS ‘26?

I just heard from a PhD student at my uni that they got an offer to be a NeurIPS reviewer. This was strange to me since they’ve never published at NeurIPS/ICML/ICLR and have only submitted to journals (not JMLR) so far.

My question — since I ever got an invite email to be a reviewer, is there somewhere I can formally apply to be considered?
