Does anyone have any resources regarding how to correctly perform the WMD skip?

Yeah, u can see it in the written guide linked by Raphael, other than that I think the only tip I can give u is practice.
Also, It's very appreciated if u can join the community discord, there we can help you faster and more directly, without needing to create a forum post that can @ a lot of players for every answer posted.
any more questions feel free to ask UwU
