Unfortunately, this Samsung adapter has not been available for months. If, like me, you absolutely need a powered USB / LAN adapter (e.g. for an iPAD if no WLAN is possible), then I can recommend the following adapter:
Baseus - USB C Multiport Adapter with USB C (PD) / 4K HDMI @30Hz / 3x USB 3.0 / VGA / SD/Micro-SD Card Reader - Dark Grey.
This is not available at Digitec though..... https://www.apfelkiste.ch/baseus-usb...
Saw that there is now something similar from Baseus at Digitec too, have a look at this one: Baseus Mirror Series Multifunctional HUB (6Ports)

The available quantity is missing, but currently it says 1-3 days, more than 10 ordered from the supplier (with CoVID-19 it can take a bit longer, but most was still delivered quickly):
Samsung Multiport Adapter (USB C, HDMI (Type A), USB A, USB Type C)

If you don't want to wait until the item is available again, I can recommend the following adapter as an alternative: https://www.digitec.ch/de/s1/product/atra-6in1-type-c-hub-usb-c-35mm-hdmi-typ-a-sd-karte-usb-a-usb-typ-c-mobilgeraet-adapter-11236257. Works perfectly with my Galaxy Tab S6.

I have both products and am satisfied with both. Please note that the Atra adapter does not have an RJ45 connector.
