Apply APM to an iFrame - The content cannot be display in Frame

I've tried multiple options such as allow_from, same_origin.

However, current DB options:

 list sys db apm.xframeoptions
 sys db apm.xframeoptions {
 value "same_origin"
 }

 list sys db apm.xframeoptions.allowfrom
 sys db apm.xframeoptions.allowfrom {
 value "https://debitcardapppp"
 }

I've also tried adding an irule to one/both VS servers

 when HTTP_RESPONSE {
 HTTP::header replace X-Frame-Options "SAMEORIGIN"
 }

I do not have the paid version of http watch and have been using fiddler. However, other than when my policy is accessed i see zero other x-frame-options.
