How to set highRefreshRate in WebXR on Oculus Go/Quest?

For WebVR I've found: vrDisplay.requestPresent ([{source: canvas, attributes: {highRefreshRate: true}}]);

For WebXR only examples with: requiredFeatures: ["local-floor"]

For requiredFeatures: ["highRefreshRate"]. I get "Unrecognized feature requested: highRefreshRate" Error in Oculus Go. Can I get supported features?

and how to set 'foveationLevel: 3'?
