How to clear browser cache in iOS as well as android.

Hi @formidableamy
Thanks for provide best library for auth.
My requirement is every time I want to clear cache when user click on login so that other user can access easily .
I mean Login prompt show every time.
I tried with additionParameters:{prompt:'login} but that is not working.
is there any props for ephemeralWebSession as well?
