Process Connectors for SAP ECC and SAP S/4HANA

Dear Celonis Team,

I have some questions for process connectors of the the Celonis Intelligent App Store.

The process connectors for SAP ECC, currently available from the Celonis Intelligent App Store, support 20 processes.
However, the process connectors for SAP S/4HANA currently only support 4 processes.

Why are there only 4 process connectors for SAP S/4HANA?
Can I use Process Connectors for SAP ECC with SAP S/4HANA?

Thanks and best regards,
Gary
