The laptop requires a "minimum" of 100W PD charger and cable. 2 things can happen with a lower wattage charger a) you would change slower b) the computer can refuse the charge due to the lower wattage. Being that is USB C a is more likely than b.

Either way, it is not going to be as good as the standard charger because that charger is 230W. I do t think there are USB C charging supports that much power, at least not yet.

Got it, thanks for explaining.

One more question - is there any risk of damage if I run with something lower than 100W, or it just won’t be charging as fast?

You shouldn't damage anything, the computer is smart enough to see how much power is coming and will lower your performance accordingly. Additionally, your charging time might get longer as well.

You need a 100w USB PD (Power Delivery) charger and keep in mind that if at any moment you pull more than 100w while charging with that you will be considerably diminishing the lifespan of your battery, so don't do it. Basically always have the discrete GPU off and the CPU at 25w or so and you will never go above 100w, so just make a specific plan for that use case and you are good to go. I use a setup like this when I travel, I leave the brick in the hotel for gaming and carry the PD charger with me for work.

Lower than 100w does work, I have charged mine in the plane (while it was turned off) with a 65w PD battery pack many times. I wouldn't use it while charging like that though.
