How to use ninjastic.space for showing address balances / USD values?

I didn't found it, I tried to search TryNinja's post history and this topic but I wasn't successful. 

I want to show how much BTC and USD value is stored on a certain address like here:

For my address: bc1qsqd6rlseaurd25uks0jvxjanuuz47x6pyuuyqd

I've really tried to find it.
