Do You Have a Urim an Tumim?

After the death of joshua, the sons of israel inquired of the lord who shall go up first for us against the canaanites. Behold, i have given the land into his hand. That sounds like a good bit of information. We have god indicating that out of the 12 tribes, judah would be the one to go up. But we do have an instance of the urim an tumim, if this is what's being used in this inquiry,. It could be an artifact from the biblical authors summarizing the event in hindsight.
