ADFS/Azure logout?

We are a Shibboleth SP and we are trying to turn on logout from an
Azure IdP.  The logout url provided to us is actually the same as
their Login URL.  It appears that ADFS/Azure IdPs are doing a logout via
a SAML transaction.

I find that if we just redirect our application to that url, following
our Shibboleth.sso/Logout, using the format:

/Shibboleth.sso/Logout?return=<azure logout url>

we get an error:

"AADSTS750054: SAMLRequest or SAMLResponse must be present as query 
string parameters in HTTP request for SAML Redirect binding."

I'm looking at these pages:

Can anybody provide some tips for how we can use this logout url?  I
tried adding the following to our shibboleth2.xml file, but the problem

        <Library path="" fatal="true"/>
