Hi,
So a sign out button only works if you are signed in. As an anonymous user, that is not yet the case. To revert back to your initial login page , you could use a microflow button.
Create a microflow that closes your page and opens your custom login page, make sure to set acces to this microflow for the anonymous user.
Hope this helps!
Hello,
You can create a regular button and change its event to Sign out. Check the example below.
