Led strip working with unknown protocol

hi there,
i bought a led strip that i’m trying to hack into dmx lights

here is the reference : https://www.action.com/fr-fr/p/3015660/ruban-led-baltimore/

it should be some adressable rgb light, i have 1 pin for color on the strip led, sending 24v through it lights the whole led strip white… idk how to do anything else, any ideas of how to find how it works ?
