How to pass options to a function (fs.readFile) wrapped inside bindNodeCallback?

[adellamaggiora]

Hello I want to use fs.readFile that has the current signature:
fs.readFile: (path: number | fs.PathLike, options: { encoding: string, flag: string }, callback: Function) => void;
but when I wrap it inside bindNodeCallback
const customRead: (path: number | fs.PathLike) => Observable<Buffer> = bindNodeCallback(fs.readFile);
I got this signature that doesn't allow me to pass options to fs.readFile function

How can I deal with it?

Thank you.
