I think you misunderstood the post.
Skier didn't have any problems creating webcam access rules, but was rather frustrated by the fact that ESET doesn't provide more granular ways to control notifications. At the current moment, whenever we use Windows Hello biometric webcam login, ESET would feel the need to bombard us with a message (upon every login, and re-login) about the authorized webcam access.
That's not just incredibly frustrating, unnecessary, but also can foreseeable prompt some users to simply disable ESET notifications altogether (amounting to an actual security risk).
