Notarizing installer


has anyone managed to get notarization working for an installer / archive? i’ve managed to notarize all the individual pieces of my app (vst/vst3/au/standalone/auv3 appext) but when i export the results, package them up with packages, and submit the corresponding .pkg (or a .dmg containing the `.pkg) i get errors from the vst/standalone/auv3 builds. just looking for advice here, i can’t be the only one trying to get this working?
