I have provisioned a SAC, embedded edition tenant in BTP. It is part of a business application using an approuter and OEM integration services, which are all working as expected.
Now I want to connect the SAC tenant to HANA using a live connection of type "Extended HANA". While the connection is shown in the tenant UI, the option "Extended HANA Live" is missing when creating a model from a data source (see screenshots). The corresponding feature toggle "OEM_LIVE_SAP_EXTENDED_HANA" is activated for my tenant as I could confirm in CIC.

Live connection of type Extended HANA.

Available data sources in SAC UI.
I already checked the following documentation artifacts but found no answer:
Starter Kit for SAP Cloud Platform Applications
Does anyone have an idea what is going on?
