peer-did-python and did-comm-python working together in didcomm-demo-python

[Tanzi005]

I am trying to run the repo 'didcomm-demo-python' but was unable to run the following imports :

from peerdid import peer_did
from peerdid.core.did_doc_types import DIDCommServicePeerDID
from peerdid.did_doc import DIDDocPeerDID
from peerdid.types import VerificationMaterialFormatPeerDID, VerificationMaterialAgreement,
VerificationMethodTypeAgreement, VerificationMaterialAuthentication, VerificationMethodTypeAuthentication

I am afraid if I am missing something. Highly appreciate your kind help!
