This documentation claims onRedirectNavigate should be in msalConfig:
https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-browser/docs/logout.md#skipping-the-server-sign-out

This documentation claims onRedirectNavigate should be passed to logoutRedirect:
https://learn.microsoft.com/en-us/entra/msal/javascript/browser/logout#skipping-the-server-sign-out

Not mentioned in the in-project documentation is adding onRedirectNavigate to msalConfig also impacts the process of logging in, and it is unclear how this affects background token refreshing.

Github docs are the most up to date and should be taken as source of truth. onRedirectNavigate should be set on the msal config but if your goal is just to clear the cache you might also try the clearCache function instead

@tnorling where is this stated?
