Does the Red Hat Single Sign-On (RH SSO) Operator supports using 'SealedSecret' objects to create the default 'admin' user?

Issue

After configuring a SealedSecret as Secret/credentials-<CR>, the RH SSO Operator is unable to create the keycloak pods with the following error message:

{"level":"info","ts":<TIMESTAMP>,"logger":"action_runner","msg":"(    0)     FAILED Update Keycloak admin secret : Object <NAMESPACE>/credential-<CR> is already owned by another SealedSecret controller <CONTROLLER>"}
