The authors' main claim We study how this effect depends on the effective masses and Rashba spin--orbit coupling parameters, extracting analytical expressions for the high electronic density regime. {Indeed, it is possible to manipulate the anisotropy introduced into the system through these parameters to achieve a boost in the Edelstein response compared to the isotropic Rashba model.} We also discuss the theoretical framework to study the inverse Edelstein effect and calculate self-consistently the electric current induced by the proximity of the system to a ferromagnet.
