How does the JWST slow down to stop in the L2?

Title sorry that's all I got. Couldn't google anything that comprehended my understanding. Please link any articles if you have any. Would love to read up on this particular part of the JWST operation. Also sorry if I don't respond immediately. Just worked a 13 hour shift and got another 11 hour shift tmrw. Need some sleep...

There are a couple of older threads about its trajectory. The gravity of Earth and Sun slow it down, it will arrive in the L2 area with almost zero speed and then make a course correction maneuver to enter its target orbit.

The rocket launched it a little bit too slow to reach L2, then JWST sped up using its own thrusters for a finer control. This maneuver was necessary because JWST cannot turn around (it would get too hot in the wrong places) - at the moment it can only speed up but not slow down.
