ADFS Proxy Replacement on F5 BIG-IP

That worked. Now only if you could tell me how to pre-populate the username-- please pretty please. I have included below the sequence of events prior to the logon page and after the logon page and was wondering if I could use the information "username=azure.token" in shown at the bottom of the first image to pre-populate the username field in the logon page. I was able to do this when I was using the F5 as the SAML iDP using an irule and check and variable assignments within the VPE (https://f5guru.com/2016/06/09/prepopulate-apm-username-from-o365-login/)
