text: There probably should be. I found one on Essex CC's public rights of way map https://www.essexhighways.org/getting-around/public-rights-of-way/prow-interactive-map.aspx -- it's PROW 209_11 which shows it going South to Epping Lane, with a fork part way along going South West that seems to come out near the NorthEast end of https://www.openstreetmap.org/way/158258585#map=18/51.66304/0.12292&layers=N. But an editor would need to visit and confirm before it could be mapped.
