Hi team 😎 🖖, I'm new with pact jvm; one question, the implementation with the local pact broker works for me. Do you know of any guide to publish my contracts in pact flow?

Publishing to Pactflow is the same as locally. You can continue to use the pact CLI

Here are a number of useful hands-on labs that teach all of the key concepts: https://docs.pactflow.io/docs/workshops and https://docs.pact.io/implementation_guides/workshops

Cool! thanks, Matt 😎
