React: return an API result from a function with fetch and add to variable?

I have this code example:

function getGameState() {
    return(fetch("http://localhost:8080/game_state"))
        .then(resp => resp.json())
        .then(data => {
            return data;
        });
};

I'm calling it from another function, like so:

function Game() {
    const gmState = getGameState()
    console.log(gmState);
}

The console output is as follows:

Promise {<pending>}

When I open up the arrow icon in the console, I see this:

Promise {<pending>}
[[Prototype]]: Promise
[[PromiseState]]: "fulfilled"
[[PromiseResult]]: Object
available: null
board: Array(1)
0: {player: 1, x: 1, y: 0}
length: 1
[[Prototype]]: Array(0)
player_turn: 2
[[Prototype]]: Object

I need to pull the data from player_turn and board so I can pass those pieces to other functions.

The only examples I've found show console.log in the last .then, which I'm able to accomplish. I tried using async and await and many variations on this. I'm not able to find any working examples, and I'm starting to wonder if this sort of pattern is possible in React.

Use async/await to fulfill the promises

async function Game() {
  const gmState = await getGameState()
  console.log(gmState);
}
