node.js – async/await for aws sdk function

I am using a custom auth challenge to get the otp as response, with below code I am able to get the OTP. But, instead of promise how can I use async/await to get the response from intiateAuth.

        const params = {
            AuthFlow: ".......",
            ClientId: "*********",
            AuthParameters: {
                "USERNAME": req.userName,
            }
        };
        return new Promise((resolve, reject) => {
            new AWS.CognitoIdentityServiceProvider().initiateAuth(params, (err, data) => {
                if (err) {
                    console.log("Error in adminInitiateAuth: %s", err.message);
                    reject(false);
                } else {
                    const otpResponse: IOTPResponseDetails = {
                        session: data.Session,
                        userName: data.ChallengeParameters.USERNAME,
                    }
                    resolve(otpResponse);
                }
            });
        });
    }```
