Hi, Cip.
I'm with Zico, of course, on that you should wait for 2.4.4, which should be there in a week. But if I got you correctly and you need to just get rid of pop-up dialog asking for permission to release scopes, you can do it by moving to "OpenID Connect -> Clients" and editing relevant OIDC client there; you need to set "Pre-Authorization" property to "Enabled" for it. These steps will also work for 2.4.4 in the future.
"oxTrust Admin GUI" is the one client you'll need to edit, but if your customer uses OIDC and creates his own client entries too, he'll need to edit this property for all of them
