VBS visual app embedded backend OIC OAuth2 credentials lost on VBCS deploy

Summary: We are calling Oracle Integrations from our VBS visual application. To achieve this the backend needs to be overridden so we can setup OAuth credentials, not an option on the environment configuration. In the VBS source these credentials are stored as a vb_ reference code and you can see these references as part of the deployment log. However, once deployed these vb_ references are not deployed correctly and the credential details for user and client id/secret are lost. Any thoughts on why these references are not working on the VBCS side? Many thanks.
