OrthoDB API: accessing hierarchical taxonomy data using R

Question

[DNAlias]

I'm interested in using the API: https://www.orthodb.org/tree to get the hierarchical tree information, and use this information in R. I've been trying to use the R package jsonlite to access this dataset. I was able to open the dataset, but it doesn't look quite right. It's not letting me access the data from the children. Is there another way I can get data from the children in R or am I restricted to javascript?
