How to Enable ASWebAuthenticationSession.prefersEphemeralWebBrowserSession on ios side for flutter sdk?

[alushpranav]

I want to remove popup on ios asking "'Example' wants to use 'xyzlogin.com' to sign in" where we have to tap continue to proceed. Some searching around shows we must enable prefersEphemeralWebBrowserSession property on instance of ASWebAuthenticationSession. Can we do it in flutter SDK? is there another way to remove it like using something other than safari or downgrading to older package? End goal is to just remove the popup.
