How to enable custom theme branding in Angular portal using oneim-api-server (v9.2)

Hello,

I am currently working on customizing the Angular end-user portal of One Identity Manager, using the official oneim-api-server Docker image, version 9.2, deployed on Kubernetes.

I would like to enable the use of custom themes located under:
/var/www/App_Data/Custom/branding/<theme-name>/
I have mounted a folder with a valid branding.json and custom.css file (structure confirmed in documentation), and the files are present and readable inside the running container.

However, no theme appears in the user interface, and the API endpoint /api/portal/branding returns an empty array.


Is it possible to enable custom theme branding in the Angular portal when using the oneim-api-server image in version 9.2?
If so, could you please clarify what needs to be configured or enabled in this environment?

Thank you in advance for your support.

Best regards,
