In American rap culture, rap artists are usually expected to write their own lyrics without significant help from other songwriters, with the exception of samples, production, and any parts of the song that are not rapped.
That's why the WAP songwriters are the rappers (Megan thee Stallion and Cardi B), the producers (Ayo N Keyz), and the songwriter of the sampled track (Frank Ski). Many other genres do not have this kind of expectation.
If you are accusing the WAP songwriters of employing ghostwriters, that is a severe allegation and needs evidence to be taken seriously.
