It is still very possible that the liquid has entered into your notebook. At this point, I would suggest that you do NOT power it back up until you had a chance to bring your notebook to the Genius Bar at your local Apple Store or Apple Authorized Service Provider to verify that no damage has occurred.
FWIW, I recently had an accidental water spill on my 2020 MacBook Pro. It was not powered on at the time. Regardless, the Apple Technician determined (& replaced) the logic board, keyboard, & trackpad. Although liquid damage is not covered under the standard Apple Limited Warranty, I elected to get the AppleCare+ plan and the repair was done at a much reduced cost to me.
