Add authorization via Steam. NodeJS - Passport JS library is available, https://www.passportjs.org/packages/passport-steam/ In fact, what is required is to add passport-steam to the package.json, slightly rewrite authentication.js and definition.yml. I can't do this on my own because I have little knowledge in the field of backend development... Please, authorized persons, give an answer, if possible, whether it will be added or not. I apologize in advance for my poor sounding language. I am not a native English speaker. Steam passportJS - https://www.passportjs.org/packages/passport-steam/
