Hi can someone please share a some content on handling multiple work flows.

what are you trying to do?

1st flow returns data and 2nd flow picks it up on 1st flows completion.

for Prefect 1.0 check out https://docs.prefect.io/core/idioms/flow-to-flow.html for Prefect 2.0, see subflows https://orion-docs.prefect.io/concepts/flows/#subflows

Thank you @Anna Geller
