We show that when a honeycomb antiferromagnetic insulator (AFMI) is sandwiched between two transition metal dichalcogenide (TMD) monolayers in a commensurate way, magnons in the AFMI can mediate an interaction between electrons in the TMDs that gives rise to interlayer Cooper pairing. This interaction opens coexisting extended s-wave and chiral p-wave superconducting gaps in the energy spectrum of the coupled system, and the latter give rise to topological Majorana edge modes.
