typescript - using instanceof on strongly typed errors always returns false

Question

I'm using a library that has a bunch of strongly typed errors that I would like to catch and handle in my code. See https://github.com/ccxt/ccxt/blob/master/ccxt.d.ts#L12

The problem is, when the library throws one of these erorrs, I'm unable to figure out which error it is. I'm currently using instanceof, but it always returns false.

What is the correct way in modern typescript to handle typed errors?

[edit] found this https://github.com/microsoft/TypeScript/issues/13965 - is it possible that it's just not a supported feature?
