Why do we use STUN servers?

If stun servers give the browser the public IP for the clients, why couldn't the signaling server give us this as well?

Or is there something else that I am missing

I was reading this here: https://bloggeek.me/google-free-turn-server/

UDP and TCP might be routed differently, in particular when there is a HTTP proxy.

Also, a signaling server will know some address of the client, but it will not know a port that going to result in a connection as one needs UDP holepunching for that.
