Question about Lenovo ThinkPad USB C-Dock

Hello, I have an E570 (https://www.digitec.ch/de/s1/product/lenovo-thinkpad-e570-1560-full-hd-intel-core-i7-7500u-16gb-ssd-notebook-6134922); do any of you use the Lenovo dock and are all functions/ports usable via the left USB-C port of the E570? Thanks for your experiences :-)
