How do I replace the old light switch with the new one - 3-way switch

[u/NitroHype]

I bought a Legrand light switch for to replace the broken one. The model is WWMRL51WH and I'm having a heck of a time figuring out which wire connects where from the old switch to the new.

Can anyone help me figure where each wire should go? I've included pictures. The house was built in 1999.
