As others have said, adding missing residues for a multi-chain protein is exactly the same as for a single-chain protein, except that you need to add chain break characters ("/") between the chain sequences. Alternatively, add the missing residues for each chain individually and then combine the two models into one, e.g. with a package such as ChimeraX.
