I know how quantum non-locality is defined in Wikipedia

quantum nonlocality is a characteristic of some measurements made at a microscopic level that contradict the assumptions of local realism found in classical mechanics. Despite consideration of hidden variables as a possible resolution of this contradiction, some aspects of entangled quantum states have been demonstrated irreproducible by any local hidden variable theory

[Wiki] and how quantum contextuality is defined in Wikipedia

Quantum contextuality is a foundational concept in quantum mechanics stating that the outcome one observes in a measurement is dependent upon what other measurements one is trying to make. More formally, the measurement result of a quantum observable is dependent upon which other commuting observables are within the same measurement set.

[Wiki]

I however can't grasp how they are related or even if they are related at all. Can anyone help me with a high level explanation?
