Possibility of opening the registration website directly / clear android browser cache and cookies

[j-q-in-berlin]

I need a "Register" button on my app. It does work when the user first opens the app. In order to do so, I set the serviceConfiguration as follows:

serviceConfiguration: {
authorizationEndpoint:
authIssuerUrl + '/protocol/openid-connect/registrations',
tokenEndpoint: authIssuerUrl + '/protocol/openid-connect/token',
},

But if I login, then logout, then hit "register" I land on the "login" page and not on the "register" page.
Any ideas how could I force it to show the "register" page each time?
Maybe clearing the cache / cookies from the android browser? Or having a prompt for the registration? Any ideas?

Thank you!
