Will the new M2 16" MacBook Pro charge with a 100W power supply?

I'm hoping to get a new M2 16" MacBook Pro for work and want a single cable set up for docking at my desk. I'm looking at an HP monitor that delivers 100W of power via USB-C. I know this set up worked when I had an i9 Macbook Pro, but it looks like the new MacBooks have a 140W power supply. I know 140W is needed for fast charging, but is 100W enough to power the new MacBooks? I want to avoid two cables if possible.

Avoid two cables...(?)

I would use the recommend charger that shipped with the Mac.

Peripheral(s) sharing the power supply, I would always have the Mac pluggged directly into the provided power supply. Depending on the load the Mac can borrow power from the battery when under demanding conditions.

There are micro processor in the magsafe charger that continually communicate with the computer to optimize both performance and charging. This unit is not passive.

Oh interesting. I didn't realize the power supply had so much going on. I like the simplicity of being able to run one USBC cable to the laptop to charge, connect to the display, and also connect to any peripherals plugged into the monitor. But it may not be worth the tradeoff in terms of the benefits of using the Apple provided power supply, especially since the passthrough wattage on the monitor I want is lower.

This is the only image I could lay my hands on currently—surprisingly complex unit on the circuit board.
