Theme json format problem

im trying to build custom theme from a json file. but it seems like some of the commands dont work.

when i try to edit pie or donut charts labels for example this is my code for piechart,

everything works but the marked lines: labelstyle and labelposition.

i cannot show the labels inside and use only data value, the default stays outside and data value, precent of toatl

if someone got a json format with all the visuals and options will be great.

Thanks
