Dell Precision 7680 requires Dell Performance WD19DC or WD19DCS docking station.
These models have two USB Type-C cables.
W9DC19 has a single USB Type-C cable. WD19TB4 has single Thunderbolt 4 cable.
240W power supply is OK with WD19DC models running Dell Precision laptops.
When light is on both cables you will get 180W to your PC. 90W / connector.
130W is not enough and will newer work so that's why you get the error message about "low charge"
WD19, WD19s and WD19TB made for Dell Latitude models. Please check the documentation:

That dock can supply a maximum of 130W to the system.
Currently, the limit for charging over Thunderbolt is 130W, so you will need to keep the 240W adapter connected directly to the system to charge it at full speed, and run it at full power.
240W docks are coming with the advent of Thunderbolt 5, but do not currently exist -- and won't help anyway since your system is Thunderbolt 4.
