Hello my friend. I had the same question. After giurs of searching i found that you need a live graphics operator. Or yoi cam use the scoreboard+ plugin on obs. For live graphics operators there is ligr live. Its almost 20 dollars an hour of streaming but it has so many possibilities. The best choice, that u started using is oberstream studio. Free and basic. But you cam easily stream a match with many graphics. Its kinda difficult to understand it but if tou check their site for information youll understand it.
