I have developed a plugin that requires replacing the body of a method in IrElementTransformer. I intend to migrate it to the FIR API of k2, but I am unsure about the process. I have consulted the k2 version of the official plugin (e.g., lombok.k2) and the classes in the org.jetbrains.kotlin.fir.extensions package. However, it appears that they only cover adding new methods and do not provide an API for modifying the body of existing methods. Does anyone have any knowledge about implementing this requirement?

IR parts of plugins (IrGenerationExtension) remains the same between K1 and K2
Migration to K2 is needed only for frontend parts (like SyntheticResolveExtension -> FirDeclarationGenerationExtension)

Check, for example, the structure of kotlinx.serialization plugin: there are `k1 `and k2 modules for frontend parts and backend module shared for both implementations
