When setting Azure AD SSO, which Logout url shall I use?

Hi,

I’m setting an Enterprise App within my Azure tenant to leverage SSO.

I know that assertion url is : <controlRoomURL>/v1/authentication/saml/assertion

However, there is no offiicial documentation about the logout url and the one that this article recommends is not working at all (i.e. <controlRoomURL>/v1/authentication/saml/logoutAssertion)

If anyone knows (from experience) which one is it please help =)

Thanks!
