There is an OK button that I am trying to edit on an Authorization Scheme page. However, I cannot find that button anywhere in the Application Builder, or figure out how to simply modify the HTML. I need to edit its onclick event so that it closes a browser tab instead of going back (<button onclick="javascript:window.history.go(-1)" class="t-Button t-Button--hot w50p t-Button--large" type="button">OK</button>).
This is the button.

I am able to edit the message on this page by editing the P30 Authorization Scheme, but I can't find where to edit the button. Please help me find this button!
