Just make sure you get a usb c to usb c 100w rated one,  this is exactly what I did and it works fine with my Ugreen dock 

What charger are you plugging into the dock with? if its the supplied one it will not work, it needs at least 100w charger - I suggest you purchase a Gan charger and try that first 

I can confirm 30w turbo is now working with my Mokin dock after the update

This is what i suspect but cant prove - i think you are right 

Yes i heard - great news
