We can confirm that the Thunderbolt 4 Dock does indeed come with its own 135W power supply.
The dock allocates 96W of power specifically for the connected host device, while the rest of the power is used for both self power and to charge connected peripherals through the Thunderbolt 4 downstream ports found on the back.
We hope this information has been able to provide a bit of clarification and guidance for you.
