I have a react js app built long time ago that uses 3rd party libraries and APIs, now I want to add this app to saleforce. Is there a way to add the existing react js app or do I have to build a new app using the saleforce development tools? Any advise and help is appreciated.

Can you live in an iframe? There's lightning:container tag that could help you. Search questions or blogs that mention it, on SO and on dedicated https://salesforce.stackexchange.com/. Iframe sounds meh but there are ways for it to communicate with parent ("canvas apps" in documentation - and it has nothing to do with <canvas> tag), silently log in to SF, use REST API...
You could try to rewrite your app to native Aura/LWC but you won't be able to call APIs directly from JS. You'll have to pass through SF server-side language called Apex. Which is doable but more for you to learn. There are some more restrictions, although light DOM and LWS help with these, many things Locker service blocks are OK in LWS.
There's also hybrid approach with loading your app as a library?
