Hi Kovas,

Thank you so much for pointing me to this github issues page and for
sharing your code! It is very helpful.

I'm having a bit of trouble with the 'react_atom_idx' property. Where did
this get set initially? If I try to run your code as written on the github
page, it does not recognize this key.

Thank you!
