Interesting, I was looking at this article from 2016:

How much UV-B does my reptile need? The UV-Tool, a guide to the
selection of UV lighting for reptiles and amphibians in captivity
Frances Baines1*, Joe Chattell2, James Dale3, Dan Garrick4, Iri Gill5, Matt Goetz6, Tim Skelton7 and Matt Swatman3

There is a chart at the end with various species and this article is mostly about how important it is to mimic the ideal environment. Here is what is listed for cane toads in this order, Biome, thermoregulatory behavior, photoperiod, microhabitat. Based on this I might try and keep her a little warmer and add a weak UV bulb.
