Is there a way I can make my XMPP (Conversations) messages synced to my desktop?

OMEMO by design does not allow old messages to be decrypted by a new device. However, anything going forward should sync between all XMPP clients that implement proper XEPs. The server also has to support the XEPs. But if you're using OMEMO, then you should also already have the other XEPs required for proper messaging experience. Specifically, the XEP for syncing messages across clients is Message Carbons.
Matrix is able to decrypt past messages on new devices, but that's because it stores your keys (encrypted) on the server and does a bunch of funky key fetching and passing between sessions to allow message decryption from new verified sessions. OMEMO does not have this function.
