Hi,
We created our own VBCS App but need to the same backend setup as DCS.
In the OOTB DCS (Digital Customer Service) app, we are able to use vb-catalog://backends.tenant/fa and it is working but in the custom app it says “Backend ”fa" not found".

I also noticed the “Override backend” is not available in the Custom App - I am guessing they are related.
Below screenshot is from DCS.

Please help us!
