Is it possible to use the CLI client to search for the Flows in a given Tenant/Project by the Flow Name? I'm trying to schedule a flow, where the user only has the display name of the Flow. I see 
client.create_flow_run
but that want's the UUID. I'm looking for a display name to UUID map, similar to how the UI does it.

Flow names aren’t guaranteed unique but we could look at doing this on a “best effort” basis — in the meantime, you could use the client to issue the GQL to grab the ID, then pass that to the 
create_flow_run
method. Here’sa quick example:
import prefect
from prefect.utilities.graphql import with_args

query = {
    "query": {
        with_args("flow", {"where": {"name": {"_eq": "YOUR FLOW NAME"}}, "limit": 1}): {
            "id"
        }
    }
}

client = prefect.Client()
result = client.graphql(query)
client.create_flow_run(flow_id=result.data[0].id)

I'll give that a shot, seems pretty straight forward!

If the flow name matches multiple, potentially you could throw an 
order_by
in to get the most recently created flow… lots of ways to ask for that ID. Once you find a pattern that works, let us know — always looking to streamline the CLI as a canonical access

I changed my approach to leverage the labels on the Flows, rather than the display name. 
query = {
    "query": {
        with_args("flow", {"where": "environment": {"_contains": {"labels": ["LABEL_NAME"]}}}, "limit": 100}): {
            "name", "version_group_id"
        }
    }
}
I need to validate that I can put multiple labels on a Flow, and have an Agent pick up the task when it's only listening for a subset of those labels, but it seems to get what I was after!
